Subject: [PATCH 1/2] manager: fix active_connection_find()
Commit 33b9fa3a3caf ("manager: Keep volatile/external connections
while referenced by async_op_lst") changed active_connection_find() to
also return active connections that are not yet activating but are
waiting authorization.
This has side effect for other callers of the function. In particular,
_get_activatable_connections_filter() should exclude only ACs that are
really active, not those waiting for authorization.
Otherwise, in ensure_master_active_connection() all the ACs waiting
authorization are missed and we might fail to find the right master
AC.
Add an argument to active_connection_find to select whether include
ACs waiting authorization.

Subject: [PATCH 2/2] manager: fix assertion failure in
active_connection_find()
Active-connections in the async_op_lst are not guaranteed to have a
settings-connection. In particular, the settings-connection for an
AddAndActivate() AC is set only after the authorization succeeds. Use
the non-asserting variant of the function to fix the following
failure:
nm_active_connection_get_settings_connection: assertion 'sett_conn' failed
1 _g_log_abort()
2 g_logv()
3 g_log()
4 _nm_g_return_if_fail_warning.constprop.14()
5 nm_active_connection_get_settings_connection()
6 active_connection_find()
7 _get_activatable_connections_filter()
8 nm_settings_get_connections_clone()
9 nm_manager_get_activatable_connections()
10 auto_activate_device_cb()
11 g_idle_dispatch()
12 g_main_context_dispatch()
13 g_main_context_iterate.isra.21()
14 g_main_loop_run()
15 main()
