Fixed deadlocking problem in armoryd

Not sure why ArmoryQt wasn't deadlocking, but the change I made
guarantees that the calls to update the wallets on new blocks
will sidestep around the BDM queue (because it's being called from
within the BDM), and thus prevent deadlocking.
Merge branch 'devel' of github.com:etotheipi/BitcoinArmory into devel
Tweaked listunspent, listaddrunspent fails with P2PKH addrs
