rows.as_csv doesn't work when using with_alias

[mbelletti]

pydal version: 20250501.2

When using a field with with_alias, rows.as_csv() fail with a KeyError, so also printing rows as:

print(rows)  

will fail.

How to reproduce:

from random import random
db = DAL('sqlite:memory')
db.define_table('test',
                Field('a'),
                Field('b'),
               )
for i in range(10):
    db.test.insert(a=str(i), b=str(random()))
db.commit()  

f = [
    db.test.a.with_alias('a'),    
    db.test.b,    
]
rows= db(db.test.id).select(*f)
print(rows.as_csv())

...
KeyError: '"test"."a" AS a'
