changing from PXBDetId/PXFDetId to TrackerTopology in CondTools

@hidaspal 
You can use `autoCond` for this test:

````
from Configuration.AlCa.autoCond import autoCond
process.GlobalTag.globaltag = autoCond['run1_design']
````
This also hides the Condition backend used (v1 or v2).
I'd suggest you move to the GT with ideal conditions for Run2.
