Editor Skin becomes grey when a Collab project is opened for the first time.

1. Create a new project in Collab and give access to the Team member.
2. Team member opens the newly created project and observes that Editor skin will become grey.

Note: It is happening when you are opening the project first time only.
Note: If the project is created with one of the fauty versions, this project won't opened properly even with the latest version (ex: 2018.2).

Final technical note:
- Project created with 2018.1.x have m_ActiveScale = 1
- When you start unity to fetch a new collab project, it creates a projectsettings.asset file where m_ActiveScale = 0;
- When fetching the project, you pass from ActiveScale 0 to 1. But no code is called to sync these values
- When the ui is painted it uses the current ActiveScale (1). But it is all paint wrong becuase the color scale are not scaled.
