detachEveryConnection seems to ignore fireEvent=false

[AbelHeinsbroek]

When using the detachEveryConnection function the system seems to ignore the fireEvent flag and still fires beforeDetach events:

detachEveryConnection is now deleteEveryConnection but fireEvent flag is still being ignored.

ex.)

plumb.deleteEveryConnection($node, {
     fireEvent: false
});

As a workaround from implementation side, I just use a flag to ignore events when deleteEveryConnection operation happens.
