[ADP-3421] Ruby E2E tests: Skip test with two cosigners (#4766)

This pull requests makes happy coins sad again. Well, actually this pull
request uses `skip` instead of `pending` for the E2E test on shared
wallets. It turns out that `pending` expects failure, while `skip`
ignores the test entirely.
