Update DocParser.php

The lines removed seem to be preventing annotations like the following:

@Foo({....}, bar="x")

I would expect to get an array with:

['value' => {....}, 'bar' => 'x'], 

instead it throws an Exception:

AnnotationException in AnnotationException.php line 42:
[Syntax Error] Expected Doctrine\Common\Annotations\DocLexer::T_CLOSE_PARENTHESIS
