Clarify zuul-cloner message about missing branch

Inform correctly about the missing branch in case that ZUUL_BRANCH is
set, but options --branch is empty.

Before:
INFO:zuul.Cloner:upstream repo is missing branch None
After:
INFO:zuul.Cloner:upstream repo is missing branch stable

Also do not print out anything when ZUUL_BRANCH nor --branch is given.
