minor test fixes WRT https://test.civicrm.org/job/CiviCRM-4.3-git/LABEL=...

these api tests were failing due to inccorect option_group_id in WHERE clause of sql query whose result is being checked by assertDBQuery, tests work after correcting the ids.

their was addition in option_group records which resulted in change of ids.
now given proper group ids of 'custom_search' and 'report_template' groups needed for test case. (verified with xml/templates/civicrm_data.tpl)
