BUG/MINOR: mworker/cli: fix the escaping in the master CLI

The master CLI must not do the escaping since it forwards the commands
to another CLI. It should be able to split into words by taking care of
the escaping, but must not remove the forwarded backslashes.

This fix do the same thing as the previous patch applied to the
cli_parse_request() function, by taking care of the escaping during the
word split, but it also remove the part which was removing the
backslashes from the forwarded command.
