Fix for multi-location breakpoints created initially as pending If the breakpoint has been created as pending breakpoint it is unknown whether it is a multi-location breakpoint or not so it has no locations. If, once the object is loaded abd breakpoint can be installed, it turns out there are multiple locations, we get an an =breakpoint-modified event listing all locations. Therefore, we have to update existing breakpoint and add locations.
