network triggers: 'verified' notification now includes wallet

Browse Source 
this is a performance optimisation.

measurements using a large wallet with 11k txns:
syncing XPUB for the first time takes 10 seconds. leaving window open, and
syncing same XPUB again in new window takes 30 seconds. in third window,
it takes ~50 seconds. then ~70s. presumably scaling linearly.
this is due to the history_list.update_item call being CPU-heavy.
now all of them take 10 seconds.
