Remove unused variable/db_get_table call.

We only hit the bug table for the summary reports
Update db_get_table() calls for remaining tables

Commit ac49ad8 adds support for the new
table name syntax,allowing us to replace db_get_table calls within queries.

Calls to db_get_table that are used by other database function,
i.e. db_insert_id, db_field_exists are deliberately left unchanged at this
stage.

This is aimed at breaking down the future DB API changes into manageable
chunks, and to aid the review process after 1.3 for 2.0.
