Lazygit crash when git worktree is delete and rename

### Describe the bug
lazygit crash when git worktree is delete and rename

### To Reproduce
Steps to reproduce the behavior:

1. Open any git repo

```sh
cd p5
```

2. Create a new worktree

```sh
git worktree add ../p5-dev dev
# Output:
# Preparing worktree (checking out 'dev')
# HEAD is now at ba90c42 vibecode subcommand
```

```sh
git worktree list
# Output:
# /home/vancanh-ng/projects/p5 077bea1 [main]
# /home/vancanh-ng/projects/p5-dev ba90c42 [dev]
```

3. Delete worktree (p5-dev) and rename main repo (p5) to the old worktree (p5-dev)

```sh
cd ..
rm p5-dev -rf
mv p5 p5-dev
cd p5-dev
```

```sh
git worktree list
# output should be like below
# /home/vancanh-ng/projects/p5-dev 077bea1 [main]
# /home/vancanh-ng/projects/p5-dev ba90c42 [dev]
```

4. Run lazygit and observe: `lazygit` run for a brief second and then crash as shown in the screenshot

Although I know I shouldn't be manually deleting and rename a git worktree and should instead use `git worktree move` and `git worktree remove`.
This still took me a while to figuring out what went wrong. So, it would be nice if `lazygit` can gracefully handle this case.

For now, I just use `git worktree prune` and move on.

### Expected behavior
`lazygit` should not crash.
