RC Init Error Spam

[mvandeberg]

With the recent changes to the RC plugin (#3589) RC accounts are being created with 0 max RC and then being updated to full without a triggering op, resulting in the follow error message on the testnet:

2704460ms rc_plugin.cpp:720             regenerate           ] NOTIFYALERT! Account gosainkund max RC changed from 0 to 110446212 without triggering an op, noticed on block 198978

The error message simply needs to check for this unique case an not emit an error message.
