Bug fixing in FastPrimaryVertex

[silviodonato]

By Martin:

Two bugs:

1. the fillDescription method ends with the wrong call:
   descriptions.addDefault(desc);
   while it should be something like:
   descriptions.add("jetVertexChecker,desc);

2. With a fillDescriptions method, you no longer need
   an explicit cfi file in the ../python directory.
   Hence, remove ../python/jetVertexChecker_cfi.py.
   (This is the file currently used by ConfDB parsing).

(2) You don't delete any file in this PR.

For 5eb060e .
Identical to #5833 (72X) though this one is actually the "original" (well it is the same tag). In both - no diffs observed in jenkins and no other issues.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_3_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?

Please do not merge this, I'm testing something.
