refactor(sql): do not expose rusqlite Error type in query_map methods

We use query_and_then() instead of query_map() function now.
The difference is that row processing function
returns anyhow::Result, so simple fallible processing
like JSON parsing can be done inside of it
when calling query_map_vec() and query_map_collect()
without having to resort to query_map()
and iterating over all rows again afterwards.
