inspector: add virtual destructor to WorkerDelegate
Browse files Browse the repository at this point in the history
Currently the WorkerDelegate class has a virtual function
but no virtual destructor which means that if delete is called on a
WorkerDelegate pointer to a derived instance, the derived destructor
will not get called.

The following warning is currently being printed when
compiling:

warning: delete called on 'node::inspector::WorkerDelegate' that is
abstract but has non-virtual destructor [-Wdelete-non-virtual-dtor]
    delete __ptr;
    ^

This commit adds a virtual destructor.
