Cyril Tovena	cd74043db9	Improve entry deduplication. (#2302 ) * Improve entry deduplication. This PR removes mostcommon and sort insert function in the heap iterator. I discovered while working on #2293 that those are actually not helping since we're deduping those lines anyways. There were no tests checking if deduping was correctly working so I did added those. Bonus point this means deduping will run faster and the code is less complex. The only side effect is that the order of entries that are at the same timestamp, before the most common entry would appear first, now we keep the same order as we stored them, which I think is better. I also change the label ordering, I think whether we are forward or backward we should keep the same aphabetical labels ordering not sure why direction was altering this before.

Cyril Tovena	d08ceef16b	Fixes iterators boundaries. (#2136 ) The start should be inclusive and the end is supposed to be exclusive. If start and end are equal, then only one entry can be returned which need to also be equal to start.
