POA duplicate nominees

[arrivets]

It is possible to nominate the same address twice, which messes things up.
The same is probably true of evictees as well.

Recompiling the master contract with solc version 0.5.11 I cannot reproduce thus behaviour. The generated bytecode.go file does have differences in the generated bytecode. I will investigate further, but if the contract can be shown to be working with a more current compiler version, I would be minded to set the pragma in solidity to the working version or higher.

Creating duplicate nominees is no longer possible but there is another problem.

A whitelist member cannot vote for the same nominee in different ballots.

Ex:
Alice is a nominee
Bob votes for her ( yes or no, doesn't matter)
Alice's application is rejected ( someone voted no ) - she gets ejected from the nominee list
Alice gets nominated again
Bob tries to vote for her again ----> BREAKS

Fixed in 4cd2afd in develop. Will be promoted to master in the release later today.
