We should ensure we populate the cache (from the changeset) before doing any other operation on `KeychainTxOutIndex` (i.e. inserting descriptors). Otherwise we will end up deriving spks which have already been cached. The test is also corrected to check that we don't duplicate deriving spks. A helper function `check_cache_cs` is added to make the tests more thorough and easier to read.

The test is also corrected to check that we don't duplicate deriving spks. A helper function
check_cache_csis added to make the tests more thorough and easier to read.Changelog notice
