// TagStringsToTags takes a slice of deduplicated, lowercase tags in the form "somehashtag", which have been
// used in a status. It takes the id of the account that wrote the status, and the id of the status itself, and then
// returns a slice of *model.Tag corresponding to the given tags. If the tag already exists in database, that tag
// will be returned. Otherwise a pointer to a new tag struct will be created and returned.
//
// Note: this func doesn't/shouldn't do any manipulation of the tags in the DB, it's just for checking
// if they exist in the db already, and conveniently returning them, or creating new tag structs.
