tdf#42316 preserve macro signature of templates
When comparing the filter of the current and the target document
we have to strip the '_template' from the filter name.
Still this won't preserve the signature of the document attached
to tdf#42316, as this is a ODF 1.0 OTT, which doesn't have a
valid signature in ODF 1.2, as the signature doesn't match the ODF
1.2 namespace for signatures and the default LO ODF version is ODF
1.2 extended.
In theory the signature itself could even be converted most times,
but that can be done in an additional patch, if needed.
Since the code literally saves a template to an internal document,
SfxObjectShell::DoSaveCompleted must keep the signature of the
template. Eventually it'll be dropped on save of the template as
a document later.
The signing tests check "OTT 1.0 => ODT 1.0: preserve", "OTT 1.2
=> ODT 1.2: preserve" and "OTT 1.0 => ODT 1.2: drop".
