Variable Names with a Leading Space Cannot be Copied

If you begin a variable name with a space, attempting to copy any instances of that blueprint will prompt an error warning: "Unknown property in <BlueprintName>: <VarName> = <Value>.

Found in 4.9.2 binary. Reproduced in 4.10 Preview 4 and Main CL 2752291.

1. Open the editor
2. Create a new blueprint
3. Create a new variable with a leading space, something like (SPACE)TestVar
4. Add an instance of the blueprint to the level
5. Duplicate the instance

Result: In the output log, notice the warning "Unknown property in <BlueprintName>: <VarName> = <Value>

Expected: Variable would duplicate without issue.
