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.
