[bugfix] parent status replied to status not dereferenced sometimes (#2587)

* much simplified DereferenceStatusAncestors(), also handles edge cases now

* perform status acceptibility check before handling even as forward

* don't further dereference ancestors if they're up to date

* call enrichStatusSafely() directly to ensure we get error messages

* change getStatusByURI() semantics to return error + old model on failed update, fix deref ancestor to check for staleness before refetch

* perform a nil-check on the status.Local variable, in case it hasn't been set on new status attempting refresh

* more consistently set returned parent status, don't check if updated

* only home-timeline statuses if explicitly visible AND not explicitly invisible!

* fix broken test now that status acceptibility checks happen on forwarded statuses
