feat: fix change when path contains any spaces

[kutiny]

This should fix #114

Despite having folder names with spaces is really abnormal, I saw people complaining about that. So I decided to fix that problem

I don't know the rules if there are for creating PRs

My solution is quite simple, whenever a path is processed from git worktree list command I changed the way it is processed, if there are more than 3 parts (I assume that the path contains at least one space) I join the parts with a space to get the correct path again.

Disclaimer: I do not know a lot of lua, I did my best with my knowledge.
