We have an issue with the events generated by starting an app. With this change during the startup of an app we transition to a failing state, which isn't acceptable, in my opinion. Se the logs below:

event: app
data: {"id":"ZXhhbXBsZXM6b2JqZWN0LWRldGVjdGlvbg","name":"Detect objects on images","description":"Object detection in the browser","icon":"🏞","status":"stopped","example":true,"default":false}

event: app
data: {"id":"ZXhhbXBsZXM6b2JqZWN0LWRldGVjdGlvbg","name":"Detect objects on images","description":"Object detection in the browser","icon":"🏞","status":"stopped","example":true,"default":false}

event: app
data: {"id":"ZXhhbXBsZXM6b2JqZWN0LWRldGVjdGlvbg","name":"Detect objects on images","description":"Object detection in the browser","icon":"🏞","status":"failed","example":true,"default":false}

event: app
data: {"id":"ZXhhbXBsZXM6b2JqZWN0LWRldGVjdGlvbg","name":"Detect objects on images","description":"Object detection in the browser","icon":"🏞","status":"running","example":true,"default":false}

We need to find a better way to distinguish between a starting app and an app with a dangling container.
