testutils: use .jj-internal git repos in most tests

Browse source 
I don't think there's much reason to run most tests with a `.git`
directory outside of `.jj`. I think it's just that way for historical
reasons. It's been that way since I added support for `.jj`-internal
repos in a8a9f7dedd.

The reason I want to switch is to make it a little easier to create
test repos for different backends. The problem with `.jj`-external git
repos is that they depend on an additional path.

I had to update `test_bad_locking.rs` to make the code merging
directories able handle missing directories on some side, because
git's loose objects result in directories getting created on one or
both sides.
