Better integrate suspend-network with unprocessed-request

Browse Source 
Also added additional safeguard against sticky unprocessed-request
status: all unprocessed-request statuses will be cleared after a
minute elapsed following intialization. The idea is that if the
user hasn't care to force a reload of the page, then it's assumed
to be by choice and uBO should stop informing about the status.
