Hange GCS path for uploading artifacts to prevent overwriting during …

…rerun

Previously every build on given branch would ovewrite files:
	gs://bucket-name/branch-name/  # first build
	gs://bucket-name/branch-name/  # rerun worklow
	gs://bucket-name/branch-name/  # new commit

Now they will be differentiated:
	gs://bucket-name/branch-name/8121a1...-140818789/  # first build
	gs://bucket-name/branch-name/8121a1...-140818789/  # rerun worklow, new files versions
	gs://bucket-name/branch-name/2323b0...-140818794/  # new commit

Wersions of reruns files could be checked with objects versioning
  (if enabled on the bucket)

It will allow better builds tracking: e.g. night-builds
