Patrol should gracefully fail if emulator is shut down during test

[dkbast]

Steps to reproduce

1. run a longer running patrol test on an android emulator
2. force quit the emulator
3. patrol cli now stuck in a loop, no exit using ctrl+c

Actual results

I was running a test which was stuck (totally fine during development) - decided to cold boot my emulator.

Now I cannot exit out of the patrol cli as its caught in this infinite loop of 'error while disposing'.

The cli should be able to terminate if there is a fatal error.

Specifically it should react to ctrl-c and forcefully close everything.
