When converting the git remote command to a builtin in 211c89 ("Make
git-remote a builtin"), a few calls to check if a remote exists were
converted from:
       if (!exists $remote->{$name}) {
       	  [...]
to:
       remote = remote_get(argv[1]);
       if (!remote)
          [...]

The new check is not quite correct, because remote_get() never returns NULL if a name is given. This leaves us with the somewhat cryptic error message "error: Could not remove config section 'remote.test'", if we are trying to remove a remote that does not exist, or a similar error if we try to rename a remote.

Use the remote_is_configured() function to check whether the remote actually exists, and die with a more sensible error message ("No such remote: $remotename") instead if it doesn't.
