Tray: Kill existing tray process

[iLLiCiTiT]

Current Behavior:

If tray is force killed and machine is restarted, the file where tray PID is stored stays in local app data, so on next tray start it can try to kill completelly different process.

Expected Behavior:

It should be able to detect if the running process by PID is actually tray or something else.

It seems I'm getting the same but with a slightly different stack trace:

Workaround

This was my workaround, delete the file in:

%LOCALAPPDATA%\Ynput\AYON\tray

That file contains the pid that Tray thinks is still running. Then launch again.
