Unity layout goes black when making a new project with imported packages

Reproduce steps

1 - Have a unity layout saved that includes a package docked in the editor (not included by default) - (e.g 2d sprite editor)

2 - Open a new project that does not contain the package

3- Part of your screen will be black and all the dock able windows in that area will not be accessible

I am expecting the inspector to show all the default windows and close all non imported ones

Workaround - You can change the layout of the screen to bring the windows back

I first tested unity 19.3.0a12 and checked unity 19.3.0a11 and 19.3.0a11 worked fine
