Controller wallet displays incorrect masternode status

[hermesesus]

Controller wallet incorrectly displays NEW_START_REQUIRED.

Controller wallet should always display the correct status of the masternode.

Instead, the controller wallet often displays an incorrect status (NEW_START_REQUIRED), while the actual status outputted by the masternode itself is: Masternode successfully started.
You have to flush mncache on the controller wallet to get the correct status (ENABLED).

Issue can be reproduced by opening the Masternodes tab on the Qt wallet (xsn-qt).

Wallet version 1.0.17 provided by official git.
Issue observed on both Linux and Windows versions.
