tdf#83722: don't recycle frame with unmodified template

a frame that contained valid but unmodified document opened from
template or explicitly opened by the user (File > New) was treated
the same as blank document i.e. it was reused and the content was
overwritten by newly opened document (even if it already had
non-empty content provided by the template).

So let's not do that and let's open a new document in a new frame
instead
