VK Fix then step for checking messagetype

[forslund]

Description

'mycroft should send the message "{message_type}"' would accept any message as the correct message. This simplifies it t use the standard "then_wait" to wait for a specific message.

How to test

Make sure the VK test for the stop skill passes Ok (only thing that uses this function)
