While testing with pagination, I noticed the pagination logic does not work correctly if you don't provide sorting logic through page object or query. It tends to bring rows already fetched in previous pages and also causes the pagination to miss fetching some data that it should have fetched.
As part of this PR, I also updated all our repository queries that fetch pages of chromosomes to be sorted by insdc_accession.

I also tried to test these changes with only querying chromosomes where md5checksum is null, but querying with the condition and modifying the chromosomes at the same time, messes with count and pagination logic, so we will have to go through the entire set of chromosomes in the assembly.
