Brian Wolff 1bb00307a8 Make generating Parser test class names more robust
This includes the extension name, and it also does much
more stringent validation. In the (now rather unlikely)
event of a duplicate name, it will append a number.

This is important, as it is very confusing when this bug strikes.
There exists extensions like CharRangeSpan which will trigger this bug.
