fix: DB helper should properly filter entries (#3359)

Browse source 
Previously it was assumed the sed operation was applying the sed expressions as a sequence, but it did not seem to filter entries being looked up correctly.

Instead any line that matched either sed expression pattern was output (_value without matching key, values split by the delimiter_), then grep would match any of that causing false-positives.

Resolved by piping the first sed expression into the next.
