Invalid amount on CoinStake transactions in the GUI

The GUI seems to include the signer reward in the amount of the CoinStake transactions.

See https://discuss.nubits.com/t/signer-reward/4378

The problem is probably here: https://bitbucket.org/JordanLeePeershares/bcexchange/src/e722d3365f673ad54afc7b25e74a2a8cc137376e/src/qt/transactionrecord.cpp?at=master&fileviewer=file-view-default#transactionrecord.cpp-51 where the transaction total output is used.
