v3.0.5: Fix isAuthRequired handling for business connections

What's Changed

• chore(): update old example with a working one by @JJ-Cro in #138
• fix(v3.0.5, #137): handling for mixed-auth connections should only auth once private topic is requested by @tiagosiebler in #139

Primarily fixes handling for topics on the business WS connection, where only some require auth.

Full Changelog: v3.0.4...v3.0.5
