Bug 13129 - HTML and JS escapes missing in unimarc_field_4XX.tt

This patch adds JS and HTML espaces are it is missing.
Replaces calls to url filter by uri filter, url filter does not espace
enough characters: http://template-toolkit.org/docs/manual/Filters.html#section_url.

Also corrects the fact the code: resul.size => resul.item('size').
Old code returns the size of the loop instead of the value of "size" field.

Test plan :
 - Use the plugin unimarc_field_4XX
 - Perform a search with a ? or &
=> Search works
 - Perform a search that returns a record with a double quote in title
 - Choose this record
=> Plugin works
 - Check the results displays well the value of biblioitems.size
