2. Squiz/OperatorSpacing: bug fix - prevent fixer conflict …

   Another one in the fixer conflict series.
   
   When running the `Squiz` standard over all test case files, a fixer conflict in the `Squiz.WhiteSpace.OperatorSpacing` sniff was discovered via the tests in the `./src/Standards/Generic/Tests/CodeAnalysis/RequireExplicitBooleanOperatorPrecedenceUnitTest.inc` file for a code sample like this:
   ```php
   $foo = $var // Comment.
       ? false // Comment.
       : true;
   
   ```
   
   The conflict essentially comes down to the `Squiz.WhiteSpace.OperatorSpacing` trying to remove the new line before the `?` and the `:` operator, but failing to do so as the new line is included in the comment token on the previous line and the sniff only adjusts/removes whitespace tokens.
   
   Original errors for the code sample added in the test case file:
   ```
    487 | ERROR | [x] Expected 1 space before "?"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    488 | ERROR | [x] Expected 1 space before ":"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    493 | ERROR | [x] Expected 1 space before "?"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    494 | ERROR | [x] Expected 1 space before ":"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    499 | ERROR | [x] Expected 1 space before "?"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    504 | ERROR | [x] Expected 1 space before ":"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
   ```
   
   The fix proposed in this PR changes the sniff to make the `SpacingBefore` error code non-fixable if the previous non-whitespace token is a comment token - even when the comment token doesn't contain a new line.
   
   While the sniff _could_ auto-fix when the comment token doesn't contain a new line, I have chosen to disable the auto-fixer for those cases anyway as it is not for the sniff to determine whether the comment should be moved, removed or should stay where it is.
   
   With these changes, the code sample in the test case file now yields the following errors:
   ```
    487 | ERROR | [x] Expected 1 space before "?"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    488 | ERROR | [x] Expected 1 space before ":"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    493 | ERROR | [ ] Expected 1 space before "?"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    494 | ERROR | [ ] Expected 1 space before ":"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    499 | ERROR | [ ] Expected 1 space before "?"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
    504 | ERROR | [ ] Expected 1 space before ":"; newline found (Squiz.WhiteSpace.OperatorSpacing.SpacingBefore)
   ```
   
   This effectively fixes the fixer conflict.
   
   :point_right: The diff will be easier to review while ignoring whitespace changes.
