Editor Crash on hot reload

[heyzxz]

Hi,

I had included "JavascriptComponent.h" in c++, and did some easy thing like this:

// JSActor is a BP actor, which already has a UJavascriptComponent attached.
UJavascriptComponent* JsCom = StaticCast<UJavascriptComponent*>(JSActor->GetComponentByClass(UJavascriptComponent::StaticClass()));

The Unreal Editor will get crash every time when I 'Build' the code (from VS).
I'm using Unreal 4.22.3 and UnrealJS 0.3.6 (which would be the currently latest version I think)

The Crash report shows below:

FYI: It looks similar with this issue: https://github.com/ncsoft/Unreal.js/issues/86 , but with different crash reports.

Hi. heyzxz. I checked how that is defined in cpp and found UJavascriptComponent class is defined by "BlueprintType" in uclass. ... it better use that in blueprint system. Thx.
