lib/workingsetcache: properly switch to whole

Previously the switch from `split` to `whole` mode had been performed too early,

Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size.
This change can reduce memory usage for data ingestion path when big number of active time series are ingested.
