Ticket 49388 - repl-monitor - matches null string many times in regex

Bug Description:  When using a wildcard(*) for the hostname, some of the
                  regex's for parsing the various configurations throws
                  out warnings.

Fix Description:  When a wildcard is detected reset the hostnode variable
                  to nothing.
