Mike Frysinger cdb344c0e7 launcher: avoid crash when executing out of checkout ...

When developing repo itself, it helps to run repo directly out of it
and to run bisection tools.  The current _SetDefaultsTo logic fails
in that situation though as it wants a branch, but the source isn't
checked out to one.  Now that we support tracking commits via the
--repo-rev setting, fall back to using the current HEAD commit.
