Remove NetworkMonitor dependency on ICaptivePortal

ICaptivePortal is used in the framework and cannot be used as a
dependency in NetworkMonitor, as the framework class takes precedence
when linking.
Also fix NetworkMonitorTest that was not verifying the right
startCaptivePortalApp call.

Test: atest FrameworksNetTests NetworkStackTests
