ui/console: unregister console from QOM tree on close

Browse Source 
Call object_unparent() in graphic_console_close() to remove the
console from /backend/console[N]. This drops the QOM tree
reference, while the initial object_new() reference keeps the
console alive for potential reuse.

When graphic_console_init() reuses a closed console, re-register
it in the QOM tree.
