* add test for emoji update image * update emoji recache to set the instance account id * don't refresh emoji if only not cached. in that case literally just recache * code comment * rename + move a few things * add some more code comments, and rename some functions to make logic a bit clearer * remove unnecessary nil check (the value can be nil) * comment wording * remove test data output * handle the case of caching an emoji which has been refreshed then uncached * allow overwriting on testrig storage as we do now on regular storage * fix emoji category ID not getting updated --------- Co-authored-by: tobi <tobi.smethurst@protonmail.com>
