fix: use correct pagination parameter in list guilds test

The guilds list endpoint uses 'limit' and 'offset' parameters,
not 'pageSize' and 'currentPage'. Update test to match API contract.

This test was sending pageSize=5 but the endpoint ignored it and
used the default limit of 20, causing the assertion to fail.
Also remove unnecessary commit() call from test setup.

Fixes test: TestAPIPaginationConsistency::test_pagination_offset_and_limit
