Fabian Reinartz 82796db37b Ensure near-empty chunks end at correct boundary 
We were determining a chunk's end time once it was one quarter full to
compute it so all chunks have uniform number of samples.
This accidentally skipped the case where series started near the end of
a chunk range/block and never reached that threshold. As a result they
got persisted but were continued across the range.

This resulted in corrupted persisted data.
