This cl/ fixes another race condition with the recent additions
to NetworkMonitorAutoDetect (getAllNetworksFromCache).
The getAllNetworksFromCache-feature uses the by the Android team
preferred way of enumerating networks, i.e to register network listeners.
Th recent fix to add IsAdapterAvailable, https://webrtc-review.googlesource.com/c/src/+/257400
contained a bug in that the adapter_type_by_name_ map was not
reset either on disconnect or Start/Stop.
This cl/ addresses that including unit test.
It also de-obfuscates NetworkMonitor so that it always
calls NotifyOfActiveNetworkList on startMonitoring even
if list.size() == 0. This should not matter but makes
code easier to understand.
