    Store: remove eds_persona_store_changed()
    
    Due to a race condition, a persona store could be available _before_ the
    signal was handled. That meant that sometimes this signal wasn't
    triggered when it really should've been. The easy fix (and imho) cleaner
    solution is to not provide any E-D-S specific behaviour, and to just
    listen to newly available backends in general.
    
    Fixes https://gitlab.gnome.org/GNOME/gnome-contacts/issues/114.
