lib/storage: code cleanup after 10f2eedee0
...
Remove the code that uses metricIDs caches for the current and the previous hour during metricIDs search,
since this code became unused after implementing per-day inverted index almost a year ago.
While at it, fix a bug, which could prevent from finding time series with names containing dots (aka Graphite-like names
such as `foo.bar.baz`).

Reason for revert: the `fetchData` arg is used in cluster branch.
