Yofi Layer Shell / Input exclusivity, doesn't get destroyed without stopping the program.

[BlockListed]

Issue

If yofi blocks after finishing the main loop, yofi's layer_shell ui and input exclusivity is still active and will soft-lock the wm.
This becomes an issue, when sending a notification with notify-send blocks for 60s when a panic occurs, thus soft-locking the wm for 60s.

Reproduce

Set a gdb breakpoint just after finishing main_inner() (currently main.rs:264) and run the program. Your wm will now be soft-locked, since the Drop impls for the wayland stuff don't actually remove the layer_shell / input exclusivity. The only time that stuff gets cleaned up is when the program exits.
