backgroundManager: Always emit 'loaded' signal

Browse Source 
As backgrounds are cached, it is possible that we never emit the
'loaded' signal added in commit f386103bc1. We are relying on the
signal though, so do the same as Background and emit the signal
from an idle if the background was already loaded.
