Unneeded shader variants are added to the bundle when using Scriptable Build Pipeline
Building asset bundles with the Scriptable Build Pipeline includes more shader variants than required
How to reproduce:
1. Open the attached project ("case_1166625-SBP_Test.zip")
2. Build asset bundles through the "Test" tab
3. Compare the sizes of the bundles
4. Check the editor logs to see how many shader variants were included in the bundles
Expected results: Scriptable Build Pipeline bundles have the same amount of shader variants as the build pipeline bundle
Actual results: Scriptable Build Pipeline bundles have more unneeded shader variants, thus being bigger in size
Reproducible with: 2018.4.3f1, 2019.1.9f1, 2019.2.0b8, 2019.3.0a8
Reproducible with package versions: 1.3.5, 1.5.0

Resolution Note:
In this case, the old building method was not able to detect some shader variants being used in other bundles and would strip them, even if they were required.
