Fixed the virtual columns to be able to use in the API with filter[]

[AparnaKarve]

Primary use case is to be able to use filter[]=archived=true in the API, which was not possible before due to the ? in the virtual column name.

Also added the active attribute/virtual column

@agrare Can you review/merge this?

We will need this change for gaprindashvili since we cannot directly query the deleted_on attribute in the API for gaprindashvili
