Related: tdf#125035 en_US formatindex="19" DATE_SYSTEM_LONG with D not DD

Otherwise CppunitTest_sw_odfimport testDateFormFormats fails with

- Expected: Wednesday, March 4, 2020
- Actual  : Wednesday, March 04, 2020

if DateFormatter uses number formatter.
This is also what
https://www.localeplanet.com/icu/en-US/index.html
lists for Date.0 and formatindex="30" has as well.

This makes adapting CppunitTest_svl_qa_cppunit testNumberFormat
necessary.
