make collection_id primary key for segment, fix system tests (chroma-…

…core#1731)

## Description of changes

- collection id should be primary key of segment table, for getSegments
performance (there will be a follow up on fixing get Segment since we
should push down collection_id)
-
https://linear.app/trychroma/issue/CHR-324/segment-table-should-have-collection-id-as-primary-key
- fixing tests broken by
chroma-core@93194c8

## Test plan
*How are these changes tested?*

- [x] passing existing tests
