Include SQL statement in exception

[zauguin]

Add the expanded query string to exceptions.
Additionally this makes the query accessible from the database_binder.

Resolves #85

I'm not sure why the test failed, it doesn't happen on my system.

Ok, it was a version problem.
@aminroosta Is there a general rule which SQLite versions we are compatible with?

[aminroosta]

@zauguin The sqlite.c & sqlite.h files in the repo (that are removed now) where v3.12.0.
Unless there is major breaking change in sqlite api, i suppose our wrapper should work with 3.x.y.
