Add test coverage for non-HTTP scheme locations

The tel:, sms: and custom scheme cases also guard the fix when running
on the JVM: the desktop JDK bundles a mailto protocol handler, so the
mailto case alone would pass even without the fix. Android's libcore
has no mailto handler and throws for all of these schemes.
