#103491 made opaque types bivariant with respect of some of their lifetime parameters. Because of this bivariance, some lifetime variables were not unified to anything during borrowck, and were considered as unequal by borrowck type test.

This PR makes type test ignore the bivariant parameters in test_type_match.

Fixes #104815
