When a persist control message with arguments is received by the anomaly detector it doesn't go through the standard chain of persistence calls, as it unconditionally rewrites the state (even if no data has been seen) and includes only the anomaly detector state rather than the categorizer state too. Because of this the memory usage was not being recalculated prior to persisting the state as would normally happen. This PR rectifies that omission. Fixes one of the problems detailed in elastic/elasticsearch#64665 (review) Backport of elastic#1585
