DATACMNS-329, DATACMNS-319 - Added test case for Repositories looking up beans by name.

Essentially a regression test that runs for Spring versions newer than 3.2.2.RELEASE and checks that repository factories are found even if not instantiated yet. This should also make sure DATAJPA-323 does not occur anymore.
