Crash when closing dot file buffers

[Hoidigan]

Summary

After creating a dot file and writing the buffer, attempting to close the buffer while viewing a different buffer causes a crash.

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', helix-view\src\editor.rs:633:51

I ran into this after trying to write a .gitignore file.

Reproduction Steps

I tried this:

1. hx
2. :w .test
3. :n
4. :bca

I expected this to happen:

The .test buffer to close.

Instead, this happened:

The program crashed

This exact location came up a few times now: #2646, #2367 (comment)

Edit: Actually, I think this is the same as the above issues. The fix was merged after the last release and I can't reproduce on current master.

@Hoidigan you can try building from source or wait for the next release which should fix your issue.
