Unity Editor crashes

[rusitschka]

We're using Unity 2017.4.13 and when running our Game in Unity Editor it runs and stops ok. When the Unity Editor is left alone in the background it always crashes after roughly 5-10 minutes - without being used.

We always see this in the Editor logs directly after the crash:

It looks like it is some Unity maintenance task to reduce memory consumption which also tries to shut down Firebase which then causes the crash. The game is not running during that time.

We've also tried Unity 2018.2.13 with the same result.

Closing as a duplicate of #200 and #191 @chkuang-g is working on this.
