Don't reject invites when pressing the ESC key
As a user I would expect ESC to close the dialogue, not take an action within it.
This is especially annoying, when having received an invite while having two clients open. One accepts the invite in the one client, but it persists in Fractal. So when one opens Fractal, it seems weird to accept an already accepted invite. My reaction to that would be to close the invite dialogue (with ESC) and close Fractal and sync up with my joined rooms. However that leads to me leaving the room, that in Fractal I haven't technically joined yet.
Steps to reproduce:
- Open Fractal
- Receive an invite
- Open the invite for the specific room
- Press ESC
