notReady - could not fetch keys

Another severe regression - this shows how lacking our tests are.

Can be tested on any account with EKM set up.

Reproduce:

1. set up account managed by EKM
2. open any encrypted message

This turns out to be an intermittent issue. It went away when I logged out and set up again. I'm moving to 0.2.1, but we have to investigate this thoroughly, it suggests we are either using Realm wrongly or not checking errors properly during setup.

Interestingly, when this was happening, it was showing 3 keys in Settings -> Keys without issue.

[Roman] After app restart it works well - seems like something isn't fully configured after sign up
I relaunched app, tapped on your message, app asked me for passphrase and loaded text after that
