If the base commit for arc patch does not exist locally, try to fetch it

Browse source 
Summary:
If the commit does not exist locally, aborting still leaves
the user checked out on the branch.  In nearly all cases, all that is
necessary is a fetch -- but the branch must also be cleaned up.  This
leads to the pattern of:
```
arc patch D12345
[...base commit does not exist...]
^C
git checkout master
git branch -D arcpatch-D12345
git fetch
arc patch D12345
```

Solve this common problem by simply trying to fetch once if the commit does not
exist locally.

Test Plan: Ran `arc patch` on a recent diff.
