NullReferenceExceptions appear in the log when using Unity 2019.4.0f1 for the first time with Bolt 1.4.12. These exceptions can be cleared and Bolt works as intended.

Regression on Unity 2019.3.15f1

Steps to reproduce
- Reinstall/Install Unity 2019.4.0f1
- Open the asset store window and download Bolt (v1.4.12)
- In the toolbar navigate to Tools > Install Bolt
- Import and continue through the Bolt Setup Wizard
- Notice issue >> After installing two warnings appear in the log along with a number of errors

Alternatively, download the bolt project from [here |https://drive.google.com/open?id=1JiXkS3nAaJVl9k3sGDwYTNRe867u8EIb]and open in 2019.4.0f1.
