tdf#111974: Ensure sufficient space for all sheets in FormulaBuffer...

and not just for the number of sheet fragments. This is important
because we changed the internal storage of FormulaBuffer from based
on std::map to std::vector in d17a83fa549f828f29e6939b16ba8b568a75f95e

Added simple unit test that loads the bugdoc in
subsequent_filters-test.cxx
