Hob: Handle NoProvider event in runningbuild module

If NoProvider event is received, we will handle it in runningbuild
module and send notification to Hob instance, avoiding stepping into the
final page with no image built out.

This fixes [YOCTO #2249]

(Bitbake rev: 067bc46a0fbc542fef1fcaa406ad3737a4c5a55a)
