[Client] Event unsubscription seems to remove all handlers

[ithr0n]

I only tested this for Alt.OnKeyUp in combination with the altv-dev-tools resource.
In my example I subscribed to this event in my own resource via Alt.OnKeyUp += Alt_OnKeyUp and at a later point I removed the subscription via Alt.OnKeyUp -= Alt_OnKeyUp.
This caused that after unsubscription the hotkeys of altv-dev-tools didn't work anymore.
When I remove Alt.OnKeyUp -= Alt_OnKeyUp from my code the resource is working without any issues.

I recognized the same issue when I have many log messages in the opened game console, especially on reconnect. Then the key listeners don’t work, probably a client issue?
