Backport 7.9: Method HstContext.isDeleteAllowed calls equals with wrong parameter

Method HstContext.isDeleteAllowed calls equals with wrong parameter. The parameter type is HstModelContext, equals expects type JcrNodeModel.
It is:
public boolean isDeleteAllowed(JcrNodeModel model) {
for (HstModelContext m : models) {
if (model.equals(m))

{ return false; }
}
return true;
}

It should be:
public boolean isDeleteAllowed(JcrNodeModel model) {
for (HstModelContext m : models) {
if (model.equals(m.getModel())) { return false; }

}
return true;
}
