[Blueprint Only] Setting a `FObjectProperty` with `FieldNotify` from Blueprint doesnt broadcast changes as others do.
Setting a `FObjectProperty` with `FieldNotify` from Blueprint doesnt broadcast changes as others do. 

The following code works as expected:
```nim
uClass UPlaceableViewModel of UMVVMViewModelBase:
  (BlueprintType)
  uprops(BlueprintReadWrite, EditAnywhere, FieldNotify):
    selectedName: FText
    total: int32
    bIsVisible: bool
    selectedIcon: UTexture2DPtr

  proc update*(selected: USolDataAssetPtr, items: TArray[USolDataAssetPtr], idx: int32) =
    if selected.isNotNil:
      self.selectedName = selected.getName().toText()
      self.selectedIcon = selected.icon
    self.total = items.num
    self.bIsVisible = items.num > 0
```
However, when setting the prop `selectedIcon` from blueprints it doesnt notify the change (it does from others). 

See the code that handles it (it gets injected in the class constructor)
```nim
proc genFieldNotifySetterAssignment(field: UEField): NimNode = 
  let setterName = ident field.name & "Setter"
  genAst(propName = newLit field.name, setterName, propType = ident field.uePropType):
    let prop = self.getClass.getFPropertyByName(propName)
    when not propType is UObjectPtr: #UObjectPtr setters has issues
      prop.setSetter(setterName)
```
