Bug 30775: Make 952w to have datepicker plugin by default

This field (Price effective from) is very similar to 952d,
but it doesn't have dateaccessioned.pl plugin by default,

Apart of worse usability of this it is also allows to enter wrong
date which will be converted in 0000-00-00 in DB and even lead to
crashes by code in other places.

So, adding this plugin not only improves usability (user can have
datepicker) but also adds date field validation.

Test plan:
1. Head over to MARC frameworks from your administration page,
check 952 subfield structure of your default framework structure.
2. dateaccessioned.pl is set as a plugin for 952d by default
but is missing from 952w.
3. Apply the patch and reset your koha, drop db and use reset_all alias.
4. Check frameworks structure again and ensure that datepicker plugin
is set by default for 952w.
5. Edit some item to ensure that datepicker works for that 952w.
