Bug 22303: Correct bottom in virtualshelves/addbybiblionumber.tt

In virtualshelves/addbybiblionumber.tt the include intranet-bottom.inc which closes the HTML last tag is not the last line of the template.

This patch moved bottom include to last line and uses popup-bottom.inc.

Test plan :
1) Permission OK :
1.1) Login in staff interface with user 'Bob'
1.2) Create a new list 'Readme' : category public and allow changes to contents from anyone
1.3) Perform a search
1.4) Check some results
1.5) Click 'Add to list' and on the list 'Readme'
1.6) A popup window opens
1.7) Check its HTML is OK, ending with </html>
2) Permission KO :
2.1) Open a new window (Firefox private session) and login in staff interface with user 'Bill'
2.2) Perform a search
2.3) Check some results
2.4) On session of 'Bob', edit list 'Readme'
2.5) Change : category private and allow changes to contents from owner only
2.6) On session of 'Bill'
2.7) Click 'Add to list' and on the list 'Readme'
2.8) A popup window opens saying 'Sorry, you do not have permission to add items to this list'
2.9) Check its HTML is OK, ending with </html>
