[Koha-patches] [PATCH] [SIGNED-OFF] Bug 10543 - false mandatory warning in additem

[Srdjan]

From: Fridolyn SOMERS <fridolyn.somers at biblibre.com>

When editing a item, you get a popup warning :
  "1 mandatory fields empty (highlighted)".
But all mandatory fields are filled.
This is because there is a field with a huge content (more than 100 characters), it it displayed in a textarea instead of input.
This patch corrects javascript form check by using siblings().
Also adds a more precise filter to find mandatory inputs because looking in full page may bring unwanted results.

Test plan :
- In a framework, make sure you have in item field :
  An optionnal subfield (without authorised value) then a mandatory subfield then an optional subfield next to mandatory subfield
  For example : $i (optional), $r (mandatory) and $s (optional)
- Open a biblio record and create a new item
- Enter more than 100 characters in $i, fill $r and $s
- Click "Add item"
- Edit this item
=> You get a textarea for $i
- Empty $s and Save
=> Without patch, you get a warning and form is not saved and you see that $s is yellow while it should be $r
=> With patch, form is saved
- Re-edit this item
- Empty $r and save
=> You get a warning and form is not saved
