Improvement: Don't read `ProfileEvents` from the server if not needed

[kavirajk]

Given now we have settings to disable profile events packet from CH server (hopefully released in next version). We can now skip reading the packet if there is no listener set for profile events.

This saves lots of bandwidth and improve performance.
