QNAM: Remove network connectivity pre-check

The connectivity pre-check has been around for a long time, and it has
caused various issues in that time. Certain scenarios, like using
certain VPN configurations, might confuse the OS into thinking you don't
have and network connectivity at all and abort the connection.
Especially noticeable/frustrating when the connection was going to a
host inside the local network.

The negative impact of this change would at worst be that we might try
to connect and it will wait some amount of time before the OS tells us
the connection failed in situations where it would previously have been
aborted before it started. But the false-negatives are not really an OK
sacrifice in that case.
