Failure to define indexes on expressions.

[masahiro-ikemoto]

On Drift-2.11.1, I was able to define indexes on expressions like this:

CREATE INDEX foo_index on foo(MAX(field1, field2));

However, after upgrading to Drift-2.12, index creation fails with the following error

[WARNING] drift_dev on foo.drift:
Could not analyze DriftElementId(package:package/foo.drift, foo_index)
type 'FunctionExpression' is not a subtype of type 'Reference' in type cast

Thanks for the report, this has been fixed in drift_dev version 2.12.1.
