tests: Make SAE roaming test cases more reliable

Browse source 
Flush the scan table explicitly to avoid issues with the ROAM command if
the new AP is not found and an entry from a previous test case is used
instead. This was happening in a number of cases where a SAE test case
was run after sigma_dut_ap_cipher_gcmp_256 which used the second AP
instance and allowed that to show up in the scan results in the next
text case.
