Adds indices to base_result and access_log

[bennybp]

Adds a unique index to base_result.hash_index. This field is used in de-duplicating procedures, so may have been a source of slowdown. This is only temporary, as we are working towards removing indices for that use case.

This also fixes/adds indices on access_log (adds one for access_type. The old index named access_type was actually the date).

Description

Adds database indices for access_log and base_result.hash_index
