Multiple instances of gurk causes Signal to become de-linked

[josephkerkhof]

Opening multiple instances of gurk causes the Signal authentication to become corrupt.

Steps to reproduce:

1. Open gurk with an already linked account.
2. Open another instance of gurk. Observe that gurk is displaying a QR code which is prompting you to link your Signal account.
3. Close all instances of gurk.
4. Open gurk. Observe that your old connection with signal is now lost.

Interesting, I'd expect the opening of the sled DB to fail immediately 🤔

I'd be happy to help contribute to a PR resolve this. I was looking at the source code for this and I think it has something to do with this code.

I'm a total n00b at rust tho, but willing to learn!

@josephkerkhof Thanks for investigating. I followed this code path deeper. It looks like the migration in presage can't open the sled db, fails and drops the current db. That's why relinking happens.

@gferon WDYT?

Definitely a bug, I can fix it.

Should be fixed in whisperfish/presage#228
