Config.h/FV8Config::GetAlias not using DisplayName metadata for typing generator

[itaib]

why was no_empty added to the if statement? with it there, the typing generator doesn't use the DisplayName metadata.
I wonder what is the use of no_empty at all in this function currently.

Alias helps you use functions like KismetFunction or FunctionLibrary with more intuitive names. However, if there is another function with the same name as the DisplayName of the function, the existing function may be erased. So I removed the part that was created with DisplayName.
