Snap package doesn't install correctly on elementary OS.

I'm a Linux newbie, just to clearness! I'm using elementary OS 5.0 Juno (built on Ubuntu 18.04.2 LTS; Linux 5.2.13-050213-generic; GTK 3.22.30). I tried to install the latest reactotron version using the snap package:
```bash
sudo snap install --classic --dangerous ./reactotron-app_2.17.1_amd64.snap
```
The app installs with no error but it shows a blank screen when launched. I installed some dependencies found in this issue https://github.com/infinitered/reactotron/issues/872#issuecomment-435872845 and tried to reinstall but the blank screen was still there.

Then I installed the deb package and it works correctly!

I thought to report this problem even though I probably didn't supply enough information. Perhaps someone else encountered it.

Reproduce the blank screen on elementary OS 5.0 Juno using the documented `snap install --classic --dangerous ./reactotron-app_2.17.1_amd64.snap` command, then compare it with the working deb package. Investigate the snap packaging or launch entry point; done means the snap installs and launches without a blank screen on the reported environment.
