don't pass project revision to UploadForReview

Passing a project revisionExpr to UploadForReview will cause it to
try to push to refs/for/<sha> if the revision points to a sha
instead of a branch.  Pass None for dest_branch if no destination
branch has been specified, which will cause UploadForReview to
upload to the merge branch.

There is room for further improvement, the user prompts will
still print "Upload project <project> to remote branch <sha>",
and then upload to the merge branch and not the sha, but that
is the same behavior that was in 1.12.2.
