Add a test demonstrating that the conflicts popup disappears

If moving a custom patch into a new commit before the original one
results in a conflict, lazygit shows the "Conflicts!" popup, but then
immediately focuses the commits view. This closes the popup, and the
user is left in a rebase that is stopped at a conflict without being
told about it.

The test uses a pre-commit hook that changes a file of the new commit;
this makes picking the original commit conflict.
