Change A:
  https://chromium-review.googlesource.com/#/c/470867/

Has a CQ dependency on change B:
  https://chromium-review.googlesource.com/#/c/470926/

Change B is in a kernel repository, on branch "chromeos-3.14", while chnage A is in chromite on TOT.

Both changes were made on a clean TOT manifest checkout, but when putting the changes through the PreCQ, the PreCQ launcher gives errors because they are not on the same branch.

"""
The Pre-Commit Queue failed to apply your change in https://luci-milo.appspot.com/buildbot/chromeos/pre-cq-launcher/8978 . CL:470867 depends on CL:470926, which was not eligible (wrong manifest branch, wrong labels, or otherwise filtered from eligible set).
"""

I've verified that labels were set incorrectly. I suspect the git repository branch name is what is confusing things, even though the "manifest branch" listed in the error is the same.
