remote: ignore failure to remove missing branch.<name>.merge

Browse source 
It is not all too unusual for a branch to use "branch.<name>.remote"
without "branch.<name>.merge".  You may be using the 'push.default'
configuration set to 'current', for example, and do

    $ git checkout -b side colleague/side
    $ git config branch.side.remote colleague

However, "git remote rm" to remove the remote used in such a manner
fails with

    "fatal: could not unset 'branch.<name>.merge'"

because it assumes that a branch that has .remote defined must also
have .merge defined.  Detect the "cannot unset because it is not set
to begin with" case and ignore it.
