Iain Lane b18896f770 {vpn,remote}-connection: disconnect signal handlers when disposed 
GNOME Settings 3.26 is crashing every time a VPN connection changed its
state. After some digging, a debug message was put on dispose, and this
issue was found:

libnm-Message: Object 0x55555633c070 disposed
libnm-Message: Object 0x55555633c730 disposed
libnm-Message: Object 0x55555633eae0 disposed
libnm-Message: Object 0x555556340a80 disposed

Thread 1 "gnome-control-c" received signal SIGSEGV, Segmentation fault.

(gdb) bt

NetworkManager is calling callbacks on disposed objects, which leads to
crashes in clients (e.g. GNOME Settings).

Fix this issue by disconnecting signal handlers when the objects are
disposed.
