Adding an action to connect to skill errors: SkillDialog not registered in factory

[ryanisgrig]

Describe the bug

When I add an action to connect to a skill, my bot throws a 500 error for:

An unhandled exception was thrown by the application.
System.Exception: virtualassistant.dialog error: Type Microsoft.SkillDialog not registered in factory

This leaves me unable to send anything to the bot.
