branch: give advice when tracking start-point is missing
If the user requests to --set-upstream-to a branch that does not exist, then either: 1. It was a typo. 2. They thought the branch should exist. In case (1), there is not much we can do beyond showing the name we tried to use. For case (2), though, we can help to guide them through common workflows.
