The current aURL conversions in the file "unoshap4.cxx"
result in the URL obtained when importing the file being replaced with a
new one formed from the presentation directory and file name.
As a result, the model changes and saving is requested
even if no changes were made to the presentation.
To fix this problem, we added saving the
presentation directory URL into the context for
transfer from SlideImpl to ViewMediaShape.
