Logging should not be used when there's a user handing the error

Context

Currently all exceptions has been logged. Example:

io.vertx.ext.web.handler.sockjs.impl.EventBusBridgeImpl:

Failure in bridge event handler

I have the same problem with the RoutingContext. See my comment at: https://github.com/vert-x3/vertx-web/commit/1fc3000071ac5e11d52e137742324e6042211ebe#r68896075

This issue should be fixed. Please reopen if needed.
