* appear inside complex formats because ::getFormats() returns NULL

/* There is a bug in ICU which prevents MessageFormatter::getFormats()
to handle more than 10 formats correctly. The enumerator could be
used to walk through the present formatters using getFormat(), which
however seems to provide just a readonly access. This workaround
prevents crash when there are > 10 formats but doesn't set any error.
As a result, only DateFormatters with > 10 subformats are affected.
This workaround should be ifdef'd out, when the bug has been fixed
in ICU. */
