Fix failing test on iOS devices #1871

[lesn1kk]

First of all, before starting this test we need to make sure that ThaliMobile is started. Otherwise, networkChangedNonTCP events will be filtered out.

Based on test assumptions that we discover 1 peer via WiFi and 1 peer via MPCF, we can safely assume that phone is connected to access point so the bbsidName field is set to some non null value. This is because networkChangedValue with bssidName set to null is treated same as WiFi off. See #1500 and #1707 for details.

Also, since this scenario assume that after disabling WiFi peerAvailabilityChanged event would be fired twice, we need to increase availibilityHandler calls limit by one.
