Fix det-pointer in tracker-rechit used in GlobalTrajectoryBuilderBase

[VinInn]

set the set-pointer as well,
related to #4179.

For what FastSim is concerned, it may remove the crash, not obvious will make the mixing meaningful

A new Pull Request was created by @VinInn (Vincenzo Innocente) for CMSSW_7_2_X.

add also the geometry pointer

It involves the following packages:

RecoMuon/GlobalTrackingTools

@nclopezo, @cmsbuild, @Degano, @StoyanStoynev, @slava77 can you please review it and eventually sign? Thanks.
@bachtis, @rociovilar this is something you requested to watch as well.

Hi all

Would reconstruction mind signing?

I was thinking on relying on Jenkins (which are fine) only but I after all I prefer now to run on a larger muon sample. If Slava is more confident (he was reviewing #4179) he can sign off now otherwise I'll run more tests.

jenkins is OK

I don't think a longer workflow on muons will show anything.
Maybe trying muon rereco from RECO inputs is something more relevant, but it seems mostly for a sanity check.

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_2_X IBs unless changes (tests are also fine).

muon rereco from RECO inputs is definitively something more relevant..
It is a workflow not exercised anywhere and we already found two critical bugs in it
thanks to fastsim reco-mixing.
I think that "muon rereco from RECO inputs" is not validated at the moment, it may even still just crash at the first event...
