[PATCH 2/2] recipetool: create: fix git URLs that only specify a tag

[Babanpreet Singh <bbnpreetsingh@gmail.com>]

A git URL with tag= and no branch= fails with:

  Unable to resolve '' in upstream git repository

AUTOREV has no branch to follow now that bitbake no longer defaults to
master. Fetch the tag itself, which also lets the branch be found from
it.

Notes:
    Tested with oe-selftest -r recipetool.RecipetoolCreateTests. Not tried
    on wrynose, which has the same code.
