Bug 36394: Fix footers behaviour on the ES mapping page

In the footers of the tables of the search fields and mappings,
the options selected are not consistent.
Additionally they are not reset correctly when a new line is added.

Test plan:
0. Do not apply to recreate the problem
1. Go to the ES mapping page
2. Click tab "Bibliographic records"
3. At the bottom, notice the Yes/No dropdown lists
=> They are inconsistent, sometimes 'Yes', sometimes 'No'
4. Click Add
=> Values are kept

5. Apply this patch
6. Repeat 1, 2, 3
=> No (first option) is always selected
7. Click Add after you modified some values
=> "No" is selected
