Union of unknown and null in generated ts types in view row

[dreinon]

Describe the bug
When ts types are generated for a view that has a column which type is not recognized by typescript, it sets the type to unknown, but since it is a view, because of the error mentioned in #577, all types have a union applied with null, and results into a type unknown | null, which throws the following eslint error:

488:26 error 'unknown' overrides all other types in this union type @typescript-eslint/no-redundant-type-constituents

To Reproduce
Steps to reproduce the behavior:

1. In a project, create a view with a column which type is not recognized by typescript, for instance, a geolocation column.
2. Generate types for that project with the cli, in a typescript+eslint project
3. Go to that view, to the Row type
4. Check the error

Expected behavior
Only unknown type with no union.
