Bug 10689: make public note appear in subscriptions search

In a serials module, when searching subscriptions, the results table as
a "Notes" column.
In TT code, you see that it tries to display public note
"subscription.notes" and internal note "subscription.internalnotes".

The internal note is displayed well but not the public note.

You can see the 2 notes in serial details in summary tab.

The problem commes from the SQL query. A join is perform on subscription
and biblio, both containing a "notes" column.

This patch solves the problem by using a alias in query for both columns
(biblio.notes is acutally not used in template but could be).

Test plan :
- Edit a subscription
- Add public and internal notes. For example : "too busy" and "on holiday"
- Perform a subscription search that returns this subscription
=> "Notes" column contains both notes. For example : "too busy (on holiday)"
- Test with only public note
- Test with only internal note

Works as described.

All tests and QA script pass.
Works as described, fixes a bug as the templates show that
the intention was to display both notes in the column.
