NB7.0 HR review for #196719 - Renaming method thru refactoring removes arguments, when arguments are annotated

http://netbeans.org/bugzilla/show_bug.cgi?id=196719

Renaming methods whose arguments have annotations lead to (incorrectly) 
incompilable code.

It is a regression since NetBeans 6.9. All existing generator tests pass 
after the fix, as do the tests created for this bug. Risk of further 
regressions should be low.

The patch has been reviewed by dbalek and verified by juhrik.
