Filter out text/uri-list with empty list
...as seen at least with the Qt6 Wasm implementation (see the code comment
for
details), and where, at least when trying to paste some plain text into
Writer,
the LO code would then favor that faux text/uri-list over text/plain, and
would
get into the
> else if( bMsg )
branch in SwTransferable::PasteFileList
(sw/source/uibase/dochdl/swdtflvr.cxx)
and try to synchronously show a message box, which for now causes an abort
in
the Emscripten build
