alternative counts of defined formats

[bansp]

This is a general note about a finding. Let's talk about it when we meet next.

https://standards.clarin.eu/sis/views/list-formats.xq in the header, counts defined formats by doing {fm:count-defined-formats()}

https://standards.clarin.eu/sis/views/list-statistics.xq in the first table uses {count(format:get-all-ids())}

-- it may be better to agree on a single way of getting this info. It's also a model vs. module difference.

Note that I have changed the above in commit 01e81bd . But the general issue remains. :-)

Moving it to the next milestone.
