variable_watch: Remove leftover debugging code (#14187)

When a watch does not specify a command to call then variable_watch
prints out a message to stderr.  Remove code after that which collects
all variable values to construct a message that is never printed.
Otherwise such code causes a READ_ACCESS watch to trigger on all
variables in the currents scope.
