Perform segwit BSQ wallet migration upon startup

Browse source 
Uncomment & enable the m/44'/142'/1' native segwit BSQ account path and
add code to migrate the user's BSQ wallet to segwit upon startup, along
the same lines as the existing BTC wallet segwit migration logic. That
is, set P2WPKH as the default output type, add a native segwit key chain
(set to active) to the BSQ wallet and back up the old 'bisq_BSQ.wallet'
file to 'pre_segwit_bisq_BSQ.wallet.backup'.

Also filter out legacy addresses coming from the original keychain from
BsqWalletService.get(Unused|Change)Address.
