tests: Fix robustness issue in DPP test cases with SAE

The sae_groups parameter needs to be cleared before attempt a SAE
connection in a test case to avoid issues with this parameter having
been left to something else than the default one by a previous test
case. This was found with the following sequence:
sae_pwe_failure dpp_auto_connect_legacy_psk_sae_1
