Fix broken tsdr feature failing the new extended SingleFeatureTest incl. TestBundleDiag due to ClassNotFoundException: odlparent.bundlestest.TestBundleDiag

The goal of this issue is to fix whatever caused a "ClassNotFoundException: odlparent.bundlestest.TestBundleDiag" when the new extended SingleFeatureTest incl. TestBundleDiag attempts to install the tsdr feature named "odl-hbaseclient", and remove the exclusion from the BLACKLISTED_BROKEN_FEATURES in SingleFeatureTest in odlparent.

Note that TestBundleDiag is a new class in the bundles-test in odlparent introduced as part of https://lists.opendaylight.org/pipermail/dev/2017-January/003106.html.

In all other projects, this works (can be found); most likely reason for it not working in tsdr must be that it creates it feature in an old way, and not use the odlparent feature-parent.
