Evan Mesterhazy cc6d290679 Fix a few minor issues with the jj prev tests
This commit adds commit graphs to most of the tests for `jj prev` to make it
clearer where `@` points before and after `prev` is run.

In addition, there were a couple of tests where the comments suggested the test
meant to have `@` pointing to a specific commit, but it actually pointed to an
empty child of that commit.

This sort of issue also exists in `test_prev_editing`. The test is supposed to
check that `--edit` is implied if you run `jj prev` on an interior commit, but
it actually caused a new empty commit to be created since `@` was sitting on a
tip commit.
