tdf#103347 PPTX import: fix duplicated slide name

PPTX import uses title text as slide names, but this resulted
duplicated slide names in the case of repeating title
text, which forbidden by UNO API:

== GenericDrawPage.idl ==

/** Gets or sets the name of this page.

<p>Duplicated page names inside a document are not allowed.
*/
[optional] interface com::sun::star::container::XNamed;

Now the import code skips the duplicated title text,
resulting default numbered slide names instead of the
duplicated title names.

Note: it seems, this hasn't fixed the jumping slide selection,
e.g. sometimes pressing Shift-F5 still presents the first slide
instead of the actual one.
