Update PHPDoc for DataDefinition

Added alternate steps to reproduce to the IS since some commenters have claimed the original steps to reproduce no longer reproduce the problem.

Opened an MR based on #24 but that also specifies NULL for getLabel() since that's what the code can actually return.

This MR fixes the "alternate steps to reproduce" that I added to the IS.

Super nit picky comment in MR;

RTBC based on the MR, hiding old patches.

Fixed line wrapping on commit:
