StaticMetadataExtractor does not map members to all annotations

[blois]

The dynamic metadata extractor maps member annotations to all AbstractNgAnnotations while the StaticMetadataExtractor only does this to the first one. The static extractor should do it to all annotations.

I'm working on the static extractor as part of #861 if nobody handles this one, I can take a look while I'm at it ?

Sure, it should be straight-forward- _foldMemberAnnotations finds all annotations which should have the member annotations folded in but then only does it on the first one- https://github.com/angular/angular.dart/blob/master/lib/tools/transformer/metadata_extractor.dart#L340

Let me know if you have any questions on it.
