Reverted changes in connect.inc based on Ulf's feedback

- Moved the ini_set() entries into a separate script 'setupdefault.inc'
- Let mysql_affected_rows and mysql_insert_id test cases use the newly created script

With the ini_set() statements inside connect.inc, some test cases would be forced to 'undo' them in order to test other scenarios.

Tested on all three dev lines with and without passing db credentials. No changes detected.
