devtool: upgrade: fix updating PV and SRCREV

This code was clearly never tested. Fix the following issues:
* Actually set SRCREV if it's been specified
* Enable history tracking and reparse so that we handle if variables are
  set in an inc file next to the recipe
* Use a more accurate check for PV being in the recipe which will work
  if it's in an inc file next to the recipe
