Improve support for trips that span more than one date

- Remove the where clause on schedule times, as it is not possible to compute a sensible driver date within the SQL query.
- Simplify the date clause comparisons
- Replace the compared date range with one adjusted with the driver duration, to catch ads that depart on a different day

* with the assumption that the query is passenger-oriented (i.e. it is up to the driver to go out of his way to pick up the passenger).
* The idea is to make a rough filter of the ads in DB to limit the number of ads to be processed more precisely by the application code.
