Whenever git returns the error "The previous cherry-pick is now empty", we would previously continue the rebase; this works for rebase because it behaves the same as "git rebase --skip" in this case. That's not true for cherry-pick though; if you continue a cherry-pick where the current commit is empty, it will return the same error again, causing lazygit to be stuck in an endless loop. Fix this by skipping instead of continuing; this shouldn't make a difference for rebase, but works for cherry-pick. Theoretically we could have a similar problem for revert (if you are trying to revert a commit that has already been undone through some other means); this should then be fixed in the same way with this change. However, the change is not relevant for revert because git returns a different error in this case.
I can't do my usual "add the tests first, with EXPECTED/ACTUAL sections that document the bug" method here, because the tests would hang without the bug being fixed. We need two different tests here: one where a cherry-picked commit simply becomes empty "by itself", because the change is already present on the destination branch (this was only a problem with git versions older than 2.45), and the other where the cherry-pick stops with conflicts, and the user resolves them such that no changes are left, and then continues the cherry-pick. This would still fail even with git 2.45 or later. The fix is the same for both cases though. The tests show that the selection behavior after skipping an empty cherry-picked commit is not ideal, but since that's only a minor cosmetic problem we don't bother fixing it here.

Lazygit would become unresponsive when cherry-picking a commit that becomes empty at the destination. There are two ways this can happen: one where a cherry-picked commit simply becomes empty "by itself", because the change is already present on the destination branch (this was only a problem with git versions older than 2.45), and another where the cherry-pick stops with conflicts, and the user resolves them such that no changes are left, and then continues the cherry-pick. This would still fail even with git 2.45 or later. The fix is the same for both cases though.
Fixes #4763.
