There is no need to enable or disable actions until the popover
is actually presented.
This also get's rid of having to be notified of changes to the
"can-add-contact" property which led to a segfault as the signal handler
was not properly cleared.
Fixes: #535
As the "can-add-contact" property is now always checked,
the menu item will be properly shown.
Fixes: #485
Shuffles some code around so that the property bindings are at the end.
This allows us to return early if there is a NULL contact (as is the case
for anonymous callers).
When introducing the per protocol dial actions we started setting the widget
self->target as the action target instead of the target property of
self->record.
Bizzarely we only sometimes got greeted with a critical:
11:30:20.5184 GLib[887977]:CRITICAL: g_variant_new_string: assertion 'g_utf8_validate (string, -1, NULL)' failed

Closes#398
Since passing a CallsContacts pointer down to every class it needs, started to
become laborous - especially since the intermediates classes don't need
the reference themselves - it was made a singleton
