ui/vdagent: send caps on fe_open

Browse Source 
The spice-vdagentd doesn't send capabilities again on host/client
disconnect (but when the session agent connects and sends a
GUEST_XORG_RESOLUTION message)

When the dbus client disconnects, vdagent_disconnect() is called to
reset the agent state. Capabilities must be negotiated again on
reconnection.
