#170 VisitAnnotation method messes up annotations (with PATCH)

[Mark Sinke]

The description of the annotation is mangled to figure out if the method should be ignored, but then passed on the superclass visitAnnotation.

The (small) attached patch fixes the issue.

These are the commit comments I would attach I would have commit rights

Fix issue with annotation instrumentation that created illegal class files
* the annotation description was unmangled for the "ignore method with annotation" feature, but then passed unmangled to the super.visitAnnotation method
* now passing the original desc to the super class method
