Fix bug preventing spaces from being used in filename (#3454)

This bug was my fault, something I changed months ago to be more
consistent with VS Code - really strange that it took months for someone
to find out spaces couldn't be used in the project panel.

~I didn't apply this fix to zed2 because I dont think the facilities are
in place to do so (@maxbrunsfeld, @mikayla-maki, is there a system in
place for this that I missed?). I did leave a TODO.~

Fix is now in zed 2.

Release Notes:

- Fixed a bug where spaces could not be inserted when editing file names
in the project panel
([#2308](https://github.com/zed-industries/community/issues/2308)).
