Bug 11707: fix editing additional attributes for patron whose category code includes a space

When editing additional attributes of a patron of a category with a
code with space (ie "CAT 3"), the Javascript is broken and Additional
attributes are not displayed.

This patch corrects by adding simple quotes around category code in JS
code.

Test plan :
- Create an patron additional attribute
- Create a new patron category with a space in code. ie "CAT 3"
- Create a new patron of this category : /cgi-bin/koha/members/memberentry.pl?op=add&categorycode=CAT 3
=> Without patch the JS is broken (Syntax error, unrecognized expression:
   [data-category_code=CAT 3]) and additional attributes are not
   displayed.
=> With patch the JS is not broken and additional attributes are
   displayed and can be edited.

In current Koha version it is not possible to create category codes
with blanks.

To test, I changed an existing category code directly in the database.
Then I followed the Test plan.
Without patch, attribute types were not displayed.
With patch, they were displayed as expected.

I recommend not using codes with spaces and fix existing ones.
Koha doesn't allow you to add category codes with spaces, so the only way
to do it is via SQL.
This patch fixes a problem and passes all tests.
