feat(repodb): DerivedImageList and BaseImageList make use of RepoDB (#1135)

- derivedImageList and baseImageList now use FilterTags to obtain results,
each with its own filter function
- images that have the exact same manifest as the one provided as a
parameter are no longer considered base images or derived images
- both calls can be made with specific pagination parameters, and the
response will include PageInfo

fix(tests): fix one of the pagination tests

The results were not reliable as the 2 returned tags were sorted by created date/time
which was not set, resulting in an unpredictable order
