Ben Boeckel 00ce12a334 variable_watch: Prevent making extra entries in the watch map ...

When removing a watch on a variable, using the operator [] on the
internal map will create an empty watch if the variable doesn't have any
existing watches. Rather than creating this empty structure in the map,
return if there isn't a watch on the variable already.
