There's objectName() and KActionCollection sets that property when an
action is added, see KActionCollection::addAction(const QString&,
QAction*). There's 1 way though to have no object name (or rather an
empty one), which is not setting an object name when creating the action
and calling addAction with an empty string (see the same function). That
one can be changed however as there's always a generated name inside the
collection.

An action automatically changes its name when its inserted into a second
collection with a different name.

And in the case of 2 collections getting the same action without a name
they both create the same internal name.
