edit: explicitly check that target commit is rewritable

Browse source 
I think the CLI should check if the target of `jj edit` is rewritable
before calling the library to update the repo. The other commands
already do that. Then, if calling `MutableRepo::edit()` fails, it's
always an internal error, which makes error handling simpler in coming
commits.
