[Users] claws-mail does not remember password even though the "Remember with password manager" option is checked

[lmfrm]

Amazingly, I found the solution!

This will get rid of the GPG password prompt so long as KeePassXC is
unlocked. Luckily gnupg is secret-tools compatible, so when prompted
and you choose 'remember password' it adds an entry into KeePassXC (if
Secret Service integration is enabled).

Thanks to everyone in the Claws mailing list who helped me understand
the mechanics of the issue.
