Copy/pasting a Custom Event that has input names containing spaces will create a Custom Event with extra inputs. It appears that an input name with a space in it will be copied as two inputs, the first with only the first word and the second with both words. User's screenshot attached.

Reproduced in 4.6.1 binary, 4.7 Preview 5, and Main (Promotable-CL-2429371)

Steps to Reproduce

1. Open any project
2. Open any Blueprint
3. Create a Custom Event
4. Add a variable of any type, named "Variable One"
5. Copy/Paste the custom event node

The new custom event node has two inputs, one named "Variable" and the other named "Variable One".
