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`).
