NetworkManager/src/nm-active-connection.c
Beniamino Galvani 02ea74c920 core: signal parent-active only when the parent AC is activated 
The parent-active signal is used by the manager to determine when the
parent active-connection is ready and a connection that depend on it
can proceed.

The AC state could transition from ACTIVATING directly to
DEACTIVATING; in such case we should not emit the signal but instead
just stop watching the parent AC.

Fixes: 6e382ea91d ('active-connection: add parent active connection tracking')
