QMacPasteBoard - protect against dangling pointers

In QMacPasteboard we use converters from QMacInternalPasteboardMime, which
has essentially a global QList of available converters.
QMacInternalPasteboardMime and derived classes register/unregister their
instances in this list (in ctors/dtors) and then QMacPasteboard is using
converters from this list. Unfortunately, when we're un-registering converter
(and this means we delete those objects) we do not remove dangling pointers
from our pasteboard objects. Apparently, this problem can be seen only when
working with macextras (thus having an access to this private API in client's
code).
