Unable to resolve alias in subquery in projection

[fulghum]

A customer getting their schema to run on Dolt has a select statement that MySQL can process, but Dolt cannot. It simplifies this this (MySQL repro):

mysql> select if (1 is not null, 1, 0) as foo, if ((select foo), 1, 0) as foo2;
+-----+------+
| foo | foo2 |
+-----+------+
|   1 |    1 |
+-----+------+

On Dolt, it errors:

dolt> select if (1 is not null, 1, 0) as foo, if ((select foo), 1, 0) as foo2;
column "foo" could not be found in any table in scope```

Fix is in GMS main, and will make it to dolt main eventually.
