Internal error during adding duplicate attribute to account
Motivation
----------
While testing I encurred the following autotest failing:

```

The problem is not with the autotest, but the code checking for the wrong error string from sqlite to transform it to a "Duplicate" type error.


Modification
------------
Modify the checks in `add_account_attribute` in `lib/rucio/core/account.py` to include the new sqlite IntegrityError message: »*(sqlite3.IntegrityError) columns account, key are not unique*«

I already have this prepared and tested.
