I updated the commit message:

update_layer.py: delete layerbranch for non-existed branch

The branch is not needed any more when it has been removed from the repo, so we
also need remove its layerbranch, otherwise it still can be got from the web,
which causes confusions.

Note, we have to move the location of tinfiol's code to avoid creating tinfoil
when not needed, otherewise, if tinfoil is created (but not needed), and the
program exists earlier before "try ... finally" block, then tinfoil.shutdown()
doesn't run so that it is not shutdown. Move the code back, right before where
it is needed can fix the problem.
