Private key with invalid user id does not recognize as missing private key for account

[martgil]

Description: A FlowCrypt android app user writes to us about an error they are getting when sending a password-protected message. The error says:

Sorry, you can't send an encrypted message. You have no private keys suitable for encryption.

This has been raised over email and then moved here to track it. The issue was caused by an invalid userid that needs to be corrected on the side of the android app.

for history. The issue was fixed by #2820. But this one will be used to fix the key creation.
