[calls] manager: Propagate messages from account

[Evangelos Ribeiro Tzaras <devrtz src gnome org>]

commit 339093876c712cd6cf890fdab063943807b848c9
Author: Evangelos Ribeiro Tzaras <devrtz fortysixandtwo eu>
Date:   Tue Dec 28 15:32:22 2021 +0100

    manager: Propagate messages from account
    
    Not all portions from the user interface are listening directly to messages from
    accounts, so the manager should propagate them to allow the UI to pick them up.
    
    Closes #340
