JavacTypeBinding.resolved(IType type) creating ResolvedSourceType with bad unique key

[robstryker]

JavaSearchGenericTypeTests.testParameterizedTypeSingleArgument02 is a test that demonstrates the bug.

The resolved source type should have a unique key like this:

Lg1/t/s/def/Generic<Ljava/lang/Exception;>.Member;

But our bindings are generating it with a key like this:

Lg1/t/s/def/Generic$Member<>;

With the incorrect key, our dom-search can't look for the proper signature.

This also causes normal search to fail if we run eclipse with the dom-based-operations but the normal search. So this is a bug in dom-based operations that needs to be fixed regardless.

Many test cases appear to be failing over this or a similar issue.

This issue also brings up the possible difference between key and signature. The API doesn't really distinguish but I know that different calls often need slightly different syntax, which is annoying. I believe I made a small PR to address this in a different part of the code earlier.
