Remove @Specialized InjectorClasses for Testing

Cdi-unit previous to 2.1.1 used weld before 2.0.2.Final which would not
allow anonymous or static inner class injection.  The TestInjectors were
added to prevent the injection of the anonymous and static inners, to
make the test environment work.  These are now removed with update to
cdi-unit jar.  Also re-added the ComponentInjectorTest to verify that
the anonymous and static-inners can be injected.  The header comments
noting the jira issue were removed as they are not applicable.
