testMethodArgumentSignatures updated to include all datatypes

updated testMethodArgumentSignatures unit test to test for equality on
all datatypes.

remove unit tests assertions with no possiblity of being true (matching
named arguments to positional and vice versa)
normalizeArguments updated to pass unit tests for all datatypes

modify normalizeArguments to not use orderedTree java object.  It wasn't
working as expected.

additionally add a work around for a ColdFusion bug where incremented or
decremented integers are converted to real numbers.
