Don't crash on exiting print preview with Notebookbar

Crash caused by this sequence (tested in Writer):

1. Closing print preview, frame is attached to controller;
2. This calls SfxNotebookBar::StateMethod
3. There notebookbar's listener is added to list of the controller's
   context change event listeners
4. Then in SwPagePreview::~SwPagePreview, notebookbar's listener is
   added to that list again
5. ContextChangeEventMultiplexer::addContextChangeEventListener
   detects second addition, and throws an unhandled exception.

I don't know why starting listening is needed in SwPagePreview dtor;
unfortunately commit d05b7b32d9ecb6fcb4a268eb68cdcee09bafa6dd doesn't
say much about context and reasons.

ControlListener is renamed to ControlListenerForCurrentController to
emphasize that it operates on the current controller of notebookbar's
frame; and its bListen parameter meaning was reverted: previously its
"true" value awkwardly meant "stop listening". All direct operations
with listener of notebookbar are replaced with calls to notebookbar's
methods.

In ContextChangeEventMultiplexer::addContextChangeEventListener,
uno::UNO_QUERY_THROW was replaced with uno::UNO_QUERY, because not
only chart controller may appear here, and it's not an error: e.g.
SfxBaseController doesn't implement lang::XServiceInfo.

Regression after commit d05b7b32d9ecb6fcb4a268eb68cdcee09bafa6dd.
