fix(cli): remove socket connection retry loop

This commit remove the socket connection retry loop in send_message
which is no longer required after @raggi's changes in
c8f6502b02.

@azinsharaf noticed that when trying to run komorebic commands while
komorebi was not accepting connections, multiple hanging komorebic
instances could be spawned, particularly if commands were retried.

@eythaann proposed an additive fix for this in PR684 but ultimately as
the previous race condition with the query/response commands has been
handed by @raggi we can remove the socket connection retry loop
completely.
