Bug 10837: make it possible to export serial claims as CSV even when no notice defined

On the serial claims page, it is possible to export (using a CSV
profile) or claim 1+ serials.
The checkboxes are not shown if the claiming notice is not defined.
So it is not possible to export claims.

Test plan:
- delete your notice "claimissues"
- go on the serial claims page
- verify that you are able to export them as CSV

This works as described and enables use of the export
funtionality even if you are not using the email notifications.
Exporting the serials will also set the claim date.
Passes QA script and tests.
