xlsx export: never export short-hand version of range address

If all the columns are in focus, LO was exporting
A10:XFD11 as 10:11.

Amazingly, we can't read that. Seriously?
Doesn't Microsoft ever export in shorthand?

I thought it would be helpful to find any instances
where LO is exporting shorthand, to verify that
we really do break import of round-tripped files.

I made a brief attempt at fixing the import,
but it will require lots of changes
and break lots of assumptions.
Obviously it can't be a hugely common problem
because I didn't find any bug reports about it...
I abandoned my attempt because it is too prone to disaster.
