Creating a new workflow definition without title throws 500

I suspect this is related to the cases when the existing titles contain parentheses like Content Approver Group: Subject group 10 (Media Studies,Technology). In which case, the following happens during the check for existing titles:
[Warning] preg_match(): Compilation failed: missing closing parenthesis at offset 47
preg_match(#Content Approver Group: Subject group 10 (Media#, My Workflow) WorkflowDefinition.php:437

Sounds like we need to preg_quote() the input before this line. Would you like to make a PR if that works for you?
