Split pins of Function inputs do not correctly update if variable type is changed

When using the inputs of a function, splitting a variable and then changing its variable type does not properly update the node as expected. This occurs with any variable type that can be split. Saving and reopening the project does not resolve this issue. This issue is not labeled a regression at this time.

Versions Tested:
4.15.3 - CL: 3450819 - Issue occurs
4.16.3 - CL: 3561208 - Issue occurs
4.17.1 - CL: 3586342 - Issue occurs

1. Create a new project (No template or starter content needed)
2. Create a new Actor class blueprint > name it "Test_BP" > open Test_BP
3. Create a new function > in the details panel under inputs > add a vector variable
4. Split the Vector variable and Increment one of the float variables
5. In the details panel for the function change the variable type of the vector
6. Compile and save the blueprint
   Result: The split pin does not update to the new variable type, even after recombining the pin
   Expected result: The pin changes variable types and disconnects from nodes properly
