7b6623558f lib/storage: skip adaptive searching for tag filter matching the minimum number of metrics if the identical previous search didn't found such filter

f4252f87e6 app/vminsert: really fix #60 
ReadLinesBlock may accept dstBuf with non-zero length. In this case the last line without trailing newline isn't read.
Fix this by comparing len(dstBuf) to 0 instead of its original length.

1458450dba app/vmselect/promql: return the correct time series from quantile 
Previously arbitrary time series could be returned from `quantile`
depending on sort order for the last data point in the selected range.

Fix this by returning the calculated time series.
