Philip Withnall 8bb9eb0fc9 keyboard: Disconnect from input source manager when destroying indicator 
When an InputSourceIndicator is destroyed, the InputSourceManager it was
connected to could (and probably will) outlive it (since the manager is
a singleton). If the InputSourceManager emits any subsequent signals,
the callbacks from the finalised InputSourceIndicator could be invoked,
and will reference finalised objects.

This can be triggered by running `pkexec true` from a gnome-terminal
window, then calling `pkill pkexec` from another terminal (on a
different VT or via SSH). This causes the dialogue to be cancelled by
polkitd.
