Do not allow wildcards with fields in select statements

[corylanou]

The following queries should not be valid:

select *, foo from bar
select foo, * from bar
select *, * from bar

[DanielMorsing]

I think there is a place for this. Consider select *, foo * 20 from bar, where the users wants to see all the fields and some derived value from it.

@DanielMorsing yes, I agree, there are several good reasons. We are putting this in here because we don't currently support it. Once the query engine has support for it, we will remove this restriction.

+1 if a TODO is added that states that this is temporary in validateWildcard

[corylanou]

@DanielMorsing I opened an issue, which is more likely to get noticed than a TODO in the code.
