Signalling isn't robust enough

[aza547]

I think we should convert the signalling checks from asserting we always get what we expect, to just handling whatever we see.

Streamlabs desktop does this.

Obviously we'll still throw an error if we get something totally unexpected, but too often we get signals like "got stop but expected stopping" - I don't know the cause for this but I'm sure it's fine and we shouldn't crash the app for it.

Example:
message (9).txt
message (8).txt
