Review Comment:
_Instead_ of calling `notLeaderException.getSuggestedLeaderAddress() `and
`getSuggestedLeaderNodeId() ` twice, first checking if non-null then setting
variables `suggestedLeaderAddress` and `suggestedNodeID`, _we can just_ call
once setting the local variables and check if variables are non-null later
before `setNextOmProxy()`.
