(Bug) Address registration error

[phahulin]

• What is it? (leave one option)

  • (Bug) report (i.e. something doesn't work as it should)

• What problem have you encountered (provide steps to reproduce if possible) / What feature are you talking about? When address info is filled, transaction is mined, but postcard is not sent because an error occurs in notify_reg_tx route.

Error seems to be in this sequence of promises https://github.com/poanetwork/poa-popa/blob/master/web-dapp/routes/notify_reg_tx.js#L23

1. there is no method getAddressTxBn exported by notifyRegTxController
2. if this method is replaced by an existing getAddressIndex method, another error happens somewhere in https://github.com/poanetwork/poa-popa/blob/master/web-dapp/server-lib/get_address_details.js
