Fix incorrect pagination in journaling

[konalegi]

This PR fixes two bugs:

• Removes the retries principle, just because Chewy::Stash::Journal.entries methods as any es query have a limit of default 10 and in case you have more than 100 they are going to be ignored. Instead, pagination is based on the total_count will scan through all entires in the journal.
• Another bug is a result of the assumption that entries in the query are sorted by created_at, but in reality, it's not.
  As an example imagine the following entries in the journal

1. Entry (id: 1, created_at: '12:01:00')
2. Entry (id: 3, created_at: '12:04:00')
3. Entry (id: 2, created_at: '12:03:00')
4. Entry (id: 4, created_at: '12:05:00')

and the current algorithm step by step

1. fetch 2 items older than 12:00:00, as a result, entries with ids 1, 3 will be fetched (src)
2. calculate the latest in the batch (src), latest created_at will be 12:04:00
3. fetch 2 items older than12:04:00, as a result, we are going have entry with id: 4 only
4. Entry with 2 will be lost

This bug fix is simple, fetch all entries ordered by created_at
