Background Android crash #23

We need to do some background stuff in our app, for this we use the background_location_tracker package which allows us to use packages aswel in the background. This is required for some different stuff, but causes an issue with your package. When in background, everything works fine, but when we want to close the isolate (since we're done), we get the following error:

kotlin.UninitializedPropertyAccessException: lateinit property torchImpl has not been initialized
...
at fr.g123k.torch_compat.TorchCompatPlugin.onDetachedFromEngine(TorchCompatPlugin.kt:107)

This blocks the cleanup process causing a memory leak and after a minute or so a error: Out of memory.
