revert part of "tdf#81765 slow loading of .ods"

it turns out that
soffice --headless --convert-to pdf tdf89833-2.xlsm
semi-reliably fails with
stl concept checking "Error: attempt to compare a dereferenceable
iterator to a singular iterator"
because we are modifying ScPatternAttr all over the place, which messes
with the sorted list in the pool.
