Describe the bug
Stashes are removed from the stash list when popped even if there are conflicts. This is different from the git standard. From git stash documentation:

pop [--index] [-q|--quiet] [<stash>]
... Applying the state can fail with conflicts; in this case, it is not removed from the stash list.

To Reproduce
Steps to reproduce the behavior:

1. Stash some changes.
2. Make some changes to a file that will cause conflicts with the stash.
3. Commit the changes.
4. Pop the stash.
5. Stash is applied and removed from the list.

Expected behavior
Stash should be applied but not removed in case of conflicts.
