In arc diff, always check that you own a revision before trying to do anything with it

Browse source 
Summary:
Some users assume they can update anything, not just revisions they own (see https://github.com/facebook/arcanist/issues/54).

Currently, if you `arc patch` or `arc amend` and get a commit message, then `arc diff` for a revision you don't own, we:

  - Fail early with a very confusing message ("You can not review a revision you own!") if you are on the "Reviewers" line, until D3820.
  - Or fail very very late with a good error message, but after lint, unit and update messages.

Instead, check that you own the revision as early as we can.

Test Plan: Tried to update revisions I didn't own, got good error messages early on (with D3820).
