lib/storage: skip metricID if the corresponding metricID->metricName is missing in inverted index during search

Browse source 
This case is possible when the corresponding metricID->metricName entry didn't propagate to inverted index yet.

This should fix the following error:

error when searching tsids for tfss [...]: cannot find metricName by metricID 1582417212213420669: EOF
