Fix row order for Welsh form CSV

The correct order for a question's details in a CSV is
 - Page heading
 - Guidance text
 - Question text
 - Hint text (if relevant)
 - List of options (if relevant)

This matches how the translations are displayed on the Welsh
Translations page

The test for this has switched from using `match_array` to `eq` so that
the ordering is taken into account.
