Bug: Removes Copy Pods Resources build phase when using cache

[CodeStage]

I have this problem with the GoogleTagManager pod, but I think it's a general problem with pod specs that define a .bundle in "resources":

• When running pod install the first time everything is fine: The Copy Pods Resources build phase for the GoogleTagManager resource bundle ("GoogleTagManager-TagManagerResources") is created
• When running pod install the second time the bundle phase is removed from the project resulting in a crash because GoogleTagManager can't find it's resources
• Deleting Pods/_Prebuild before every pod install helps as a workaround, because then the build phase is not removed
• I'm not using all_binary! in my Podfile, but I testet it and it doesn't make a difference

What's your environment:

CocoaPods : 1.8.4 Xcode : 11.3.1 (11C504) cocoapods-binary : 0.4.4

A demo project is helpful:

• To reproduce it, it's enough to add GoogleTagManager pod to the demo project
• It can be observed with the demo project that the "GoogleTagManager-TagManagerResources" build phase disappears as described above (but it does not crash because GoogleTagManager is not configured properly so it doesn't run)
• BinaryDemo.zip
