tests: Make eap_check_auth() error on missing selectedMethod clearer

It was possible to hit an error case in ap_wpa2_eap_in_bridge where the
selectedMethod STATUS field was not available. This resulted in not very
helpful "'selectedMethod'" message in the test log file. Make this
clearer by dumping all received STATUS fields and a clearer exception
message indicating that selectedMethod was missing.
