Your issue looks related to the name of the event. The WebChat is sending an event named requestWelcomeDialog, where your bot code is looking for an event named webchat/join. If you change one of them, it should work.
There are two possibilities for handling welcome messages.
Conversation Update. DirectLine broadcasts a conversation update event by default, however this is not preferred. This event will end up in OnMembersAddedAsync.
Custom Event. Send a custom event using WebChat v4, as described in this sample. This event will end up in OnEventActivityAsync.
My advice would be to upgrade to the new WebChat (v4) and to have a look at this sample. The ConversationUpdate has limitations and you are more flexible by sending a custom event.
