Output getmininginfo

#### What happened:

- timelock wrong when more than 1 Operator per Node, only first(?) Node in output
- Operator shows Legacy-Operatoraddress, but Logfile shows Threadstaker, no assignment without external tools between Operator and Threadstaker possible?

#### What you expected to happen:
Show correct timelock for each masternode.
Possibility to see which Threadstaker mint for which Operator or show both in getmininginfo.

#### What are your environment parameters:
AIN 1.8 Latest Release in Testnet


Start at the getmininginfo entry point and trace how timelocks and Operator/Threadstaker assignments are assembled when a node has multiple operators. Done means the output reports the correct timelock for every masternode and makes each Threadstaker-to-Operator relationship identifiable without external tools.
