PCG graph always resave in the ResavePackage commandlet

The package that contains the PCGGrapch is dirtied on load (UPackage::SetDirtyFlag) which triggers a resave operation.

I traced it back to the following callstack:
UnrealEditor-CoreUObject.dll!UPackage::SetDirtyFlag(bool bInIsDirty) Line 102 C++
UnrealEditor-CoreUObject.dll!UObjectBaseUtility::MarkPackageDirty() Line 335 C++
