Models using excluded render paths with shader variants disabled in deferred rendering do not render in preview window
Steps to reproduce:
1. Open attached project
2. Select Cube in Project view
3. In Inspector set Shader property to "Custom"->"PreviewBugTest"
-Preview window becomes empty
Problem: Models using excluded render paths with shader variants disabled in deferred rendering do not render in preview window
Actual result: setting "exclude_path:forward exclude_path:prepass" in shader models are not rendered in preview window
Expected result: models should render in preview window
For cube to be rendered again, just comment out "exclude_path:forward exclude_path:prepass" part in shader on 16 line

We just ran into this issue as well. We're
A simple vert-color only shader compiles to 1116 lines with Forward rendering enabled, vs. only 524 lines with "exclude_path:forward".
So basically we're having to compile quite a bit more *just* to see the preview. Pretty annoying.
