Steps to reproduce:
1. Create new Unity project
3. Import Easy_Save_v2.7.1p1 package
4. Notice that both prefabs in EasySave2/AutoSave lost their script references

Expected result: script references should not be missing when the package is imported

Note: When the project is imported in 2017.1.0-5.5.x the following error appears - error CS1704: An assembly with the same name `UnityEngine.UI' has already been imported. Consider removing one of the references or sign the assembly
C:/Program Files/Unity 5.5.1f1/Editor/Data/UnityExtensions/Unity/GUISystem/UnityEngine.UI.dll (Location of the symbol related to previous error)

Reproduced in: 2017.1.0a4, 5.6.0f3, 5.5.1f1
Working in: 5.2.3f1, 5.3.6f1, 5.4.2f1
