ProjectionList{ColumnList{...}}.As("some_alias") results in no columns being rendered in the SQL about jet HOT 2 CLOSED

Opened PR with fix.
Another thing I'd like to have is ability to use As("") to remove table prefixes from aliases:

	selects := mysql.ProjectionList{
		strain.StrainID,
		strain.StrainName,
	}.As("")
	q := mysql.SELECT(selects).FROM(strain)
	fmt.Println(q.DebugSql())

Actual output:

SELECT strain_minimal.strain_id AS ".strain_id",
     strain_minimal.strain_name AS ".strain_name"
FROM company.strain AS strain_minimal;

Desired output:

SELECT strain_minimal.strain_id AS "strain_id",
     strain_minimal.strain_name AS "strain_name"
FROM company.strain AS strain_minimal;

But maybe this deserves its own method?

I think we can use the same method. If empty string is passed it should be safe to remove a dot. QRM will work regardless of dot, and I don't think anyone currently uses this kind of aliasing.
