UObject Macro Libraries cannot use functions that require a WorldContext

If you make a Blueprint Macro Library that derives from UObject you are then unable to use any functions that require a WorldContext, like Delay. This is because the WorldContext cannot be assumed like it would if the MacroLibrary derived from Actor. 

This was requested specifically to allow for UObject MacroLibraries that can be used for both Components and Actors, both of which have a valid WorldContext but UObject is their common ancestor. 

1. Open the Editor
2. Create a Blueprint Macro Library that derives from Object
3. Right click and type "Delay"

Actual Result: The delay function is not shown, like it would if this were a Macro Library deriving from Actor
Expected Result: The delay function should be shown as an available function to use
