fix(profile): use clientedit for description, add sendCommandNoWait

Description via clientupdate is rejected (error 1538) on TS3 full-client
protocol. Switch to clientedit on the bot's own clid, which is how
TS3AudioBot handles it. Requires b_client_modify_description permission.

Also add sendCommandNoWait to TS3Client for fire-and-forget commands
(clientupdate, channeledit) that don't return timely responses.
