Fix request parsing

[Galiley]

Split already parsed query parameters by the Application (Express for instance)

Hi @Galiley, could you explain the rationale for the first change?

Maybe add a test to explain the case you’re fixing with this change

[Galiley]

The reason behind that is kinda related to #144

[anttiviljami]

Any chance you could device a test that demonstrates this to document better what's being fixed?

Since this change affects how all requests are parsed and while I don't see any huge issues here, I'm a little uncomfortable merging without fully understanding the need for this change.

[Galiley]

While trying to make some tests, I've found out that the change I've made in the handleRequest method was kinda useless.
That's why I'm reverting my changes

Sorry, I'm really struggling to understand what problem this PR is solving so I've decided to close it. Feel free to reopen and give a better explanation of why this is needed.
