Initialization error when creating FEventReply objects from Python

the handled value passed to unlock_mouse is actually treated as unhandled, because FEventReply has no uproperty and no Identical()function of its own. Adding WithIdenticalViaEquality can fix this issue 

run python code in editor:

import unreal
handled = unreal.WidgetLibrary.handled() 
unreal.WidgetLibrary.unlock_mouse(handled)

Add a breakpoint in ::UnlockMouse and check the value of "Reply"

it's actual value is "unhandled", expect to be "handled"
