Bug 22082: ambiguous column in patron stats

In Reports > Patrons statistics, the combination of activity and extended attributes generates an invalid SQL query with error :
ERROR 1052 (23000): Column 'borrowernumber' in IN/ALL/ANY subquery is ambiguous

This is because FROM contains tables borrowers and borrower_attributes both containing borrowernumber column.

Test plan :
1) Be sure to have a patron extended attribute
2) Be sure you have some recent circulation activity
3) Go to Reports > Patrons statistics
4) Select 'active' in 'Patron activity' and 1 years of activity
5) Check 'Row' in 'Patron category'
6) Check 'Columns' in a extended attribute
7) Submit
8) Without patch you have no results, with patch you have exepected results
