The issue arises when the network becomes validated based on the
isCaptivePortal success with HTTPS, even though the HTTP probe
hasn't been executed yet. Given that there is no way to ensure
HTTP probe was sent in this case, the pass condition should be
relaxed, allowing a single https query instead of expecting both.

Test: atest FrameworksNetIntegrationTests:ConnectivityServiceIntegrationTest#testValidation \
      --rerun-until-failure 100
      (With hardcoded sleep when starting HTTP probe)
