xmlsecurity OOXML export: only cache existing signatures, not our temp. one

When adding a signature, first we export it to a temp. storage, then
read it back, show the verification to the user, and then later we do or
do not write the temp. storage back to the original one.

This means the signature gets exported two times, and MSO only considers
the final result valid. So when caching signatures (to avoid a real
export based on our data model), don't cache the one we just added to
the temp. storage, but do a real export second time as well.

With this, MSO considers our appended signature (next to an existing
one) valid, too.
