Handle master branch deletion.

If the master branch is deleted, this typically means we are obsoleting our
package.

Rather than 'deal' with the branch deletion, simply rename the repository
and then continue.

We will likely have to deal with a later resurrection and also deal with
package renames better too (e.g. one commit renames and resurrecting
a specific package that was subsequently brought back from the dead)
but this will be dealt with in a later commit.
