fix(engine/sqlite): fixed detection of column alias without AS

[orisano]

fix #2559

[kyleconroy]

For end-to-end tests, the query should be consistent across engines. In this particular case, either create a new end-to-end test or create a second named query in query.sql, adding it to the MySQL and PostgreSQL test cases as well.

@kyleconroy fixed!

I think this will need a rebase or merge from main to get tests running again.

@andrewmbenton rebased!

Looks good to me. @kyleconroy do these tests look alright?
