Fix unit test errors in DocsHelper_AddTrackRowTest.java

DocsHelper_AddTrackRowTest is using a MockContext, which
cannot be used to call DateFormat.getDateFormat(context).

Refactor a getDisplayDate method in DocsHelper and allow the
test to override the method.

Also update .hgignore to AnnotationProcessor.log.
