[tests] Added smoke tests for supertype/interface type completionrefs/changes/82/9482/7

If completion is triggered behind extends or implements, there is no
prefix typed so far, and enclosing types supertypes and/or interfaces
are retrieved from the completion context, a bug is triggered in the JDT
which causes an IllegalArgumentException to be thrown.
