impr(profiling): always remove launch profile config after starting

[armcknight]

I realized after rereading #3637 (comment) that even if we consider a launch profile unable to be stopped as a misconfiguration we can't currently avoid at runtime, this leads to every launch afterwards also starting the launch profiling. We should instead consider not starting the SDK as disabling launch profiling, the same as if the SDK had never been started in an app.

To achieve this we should always remove the config file once we're done with it. Configuring to disable launch profiling already removed any file present; now, starting the launch profiler also removes it.

Leaving as a draft until I can write/modify a test for it.
