[chore] Tidy up some of the search logic (#1082)

Browse Source 
* start refactoring some of the search + deref logic

* add tests for search api

* rename GetRemoteAccount + GetRemoteStatus

* make search function a bit simpler + clearer

* fix little fucky wucky uwu owo i'm just a little guy

* update faulty switch statements

* update test to use storage struct

* redo switches for clarity

* reduce repeated logic in search tests

* fastfail getstatus by uri

* debug log + trace log better

* add implementation note

* return early if no result for namestring search

* return + check on dereferencing error types

* errors hah what errors

* remove unneeded error type alias, add custom error text during stringification itself

* fix a woops recursion 🙈
