Renaming an input pin does not update accessor

1. Launch the editor.
2. Create a new Blueprint class.
3. Add a new function (MyFunction).
4. Add a new input to the function of type 'Integer' (MyInput).
5. Compile.
6. Right-click in the 'MyFunction' graph and choose 'Get My Input' to add an input accessor node to the graph.
7. Rename the input to something else. Note that the accessor does not change name.
8. Compile.

Note that the accessor is now in an invalid state unable to find the property related to it.

[Bug] Function input as variable: changing input name / type does not propagate to references
