[epiphany/wip/sync: 52/52] sync: Let EphyShell start the sync after sign in



commit 032b5d4fa5b19b82ec32461aea20205503e380c2

    sync: Let EphyShell start the sync after sign in
    
    It's wrong to trust PrefsDialog to start the sync because the preferences
    dialog can be closed while EphySyncService is signing in, therefore
    causing the STORE_FINISHED signal callback in PrefsDialog to not be
    called.
