git::repo does not update remote URL if it changes.

If you change a git::repo source parameter, e.g.

git::repo{'foo':
  path    => '/usr/src/foo,
  source  => 'git://github.com/me/foo.git',
}

to

git::repo{'foo':
  path    => '/usr/src/foo,
  source  => 'git://github.com/you/foo.git',
}

And does nothing.

While doing the same and changing the branch (iff the new branch does not exist on the old remote):

git::repo{'foo':
  path    => '/usr/src/foo,
  source  => 'git://github.com/me/foo.git',
  branch  => 'master',
}

to

git::repo{'foo':
  path    => '/usr/src/foo,
  source  => 'git://github.com/you/foo.git',
  branch  => 'baa',
}

results in the error:

Error: /usr/bin/git checkout baa returned 1 instead of one of [0]
Error: /Stage[main]/Puppetdashboard::Install/Git::Repo[puppet-dashboard]/Exec[git_puppet-dashboard_co_branch]/returns: change from notrun to 0 failed: /usr/bin/git checkout baa returned 1 instead of one of [0]

...well because the baa branch doesn't exist.

A workaround is to either delete the repository on the target server and have puppet recreate it on the next run, or manually change the remote to a new URL with:

git remote set-url origin 'git:/example.org/path/to/repo.git' -b branch
git fetch origin
git reset --hard origin/branch

Ran into this as well.
I think the 'set-url' could be called if the current url does not match the source provided.
