Cryptic error returned if you have local changes

[willcl-ark]

If you have local changes and try to run gh worktree pr [num] <path> without first commiting or stashing, then you see a seemingly unrelated error message, e.g.

$ gh worktree pr 12345 /home/will/src/project-12345
fatal: invalid reference: RemoteBranchName
Error: exit status 128
Usage:
  worktree pr [pr number] <path> [flags]

Flags:
  -h, --help   help for pr

exit status 128

Running with git shows the full issue:

$ gh pr checkout 12345

Aborting

Would be neat if this plugin propagated errors a bit more fully?

Ps thanks for the plugin, really enjoy it!
