Input values for Select Value nodes all display the same name as the output variable name when connected to a blueprint variable

[jdaignault]

Upon connecting a Select Value node to a Set a Property node associated with a blueprint variable, the display names of the input values all update to match with the output value's name.

Steps to reproduce:

1. Create a widget, and within it declare a new blueprint variable of type bool
2. Create a binding with a Field Notify node, and choose Visibility for its property path
3. Create a Select Value node and connect its input to the output of the Field Notify node
4. Create a Set a Property destination node, and choose the new blueprint variable for its property path
5. Connect the input of the Set a Property node with the output of the Select Value node
6. Observe that all of the input names for the Select Value node display the name of the blueprint variable, instead of the enum value display names
