Failed to disable WireGuard tunnel on Android

[baltpeter]

Another bug that came up during the tweaselORG/meta#16 run:

Failed to analyze app /media/benni/storage2/tmp/tweasel/cert-pinning-experiment/de.zollsoft.arzt_direkt_app-96.apk: Error: Failed to disable WireGuard tunnel.

    at <anonymous> (/home/benni/coding/JS/tweasel/experiments/cert-pinning-bypass/run.ts:82:17)

From then on, every other app unsurprisingly failed with:

Failed to analyze app /media/benni/storage2/tmp/tweasel/cert-pinning-experiment/de.zooplus-161421209.apk: Error: Cannot start new traffic collection. A previous one is still running.

On the device, the tunnel is in fact still enabled.

Running adb shell am broadcast -a com.wireguard.android.action.SET_TUNNEL_DOWN -n 'com.wireguard.android/.model.TunnelManager$IntentReceiver' -e tunnel appstraction manually doesn't help.

Even starting the WireGuard app and running the command didn't help.

And neither did force-stopping the app.

After manually disabling the tunnel in the app and re-enabling it, I still cannot control it via intents.

Curiously, just rerunning the analysis script did work. I don't think ensureDevice() should have changed anything, so maybe the solution was to re-enable the tunnel via an intent, even though it was already enabled?
