Database::get_table currently either returns a RefPtr to an existing table, a nullptr if the table doesn't exist, or an Error if some internal error occured. Change this to return a NonnullRefPtr to an exisiting table, or a SQL::Result with any error, including if the table was not found. Callers can then handle that specific error code if they want. Returning a NonnullRefPtr will enable some further cleanup. This had some fallout of needing to change some other methods' return types from AK::ErrorOr to SQL::Result so that TRY may continue to be used.
