glib/gio/tests/network-monitor.c
Iain Lane ec20cb4402 tests/network-monitor: Always use the dummy proxy resolver 
If glib-networking is installed and built with libproxy support, this
test will use it. If a proxy is set in the environment, we might get
correctly told to go through it for certain accesses. However, this isn't
going to work, because the testsuite monkeys with the network monitor to
tell it that all addresses - including the proxy - aren't reachable.

We're trying to check if adding networks to a GNetworkMonitor works in
general. Proxies just get in the way here, so let's use the built in
dummy proxy resolver which just tells us that all URLs are directly
accessible.
