use fully-qualified name for Vector in generated code

[cornerman]

This is to avoid name-clashes with types from the graphql schema, i.e.,
if a type is called Vector.

Example:
enum ImageType {
Raster
Vector
}

We encountered some edge cases with the line length - regarding the scalafmt config. Therefore, we had to add a line-break in one of the test cases. Does it make sense to pass the expected-code through the formatter as well?

Hmm, I think that's fine as it is. Might be difficult to find differences if we call the formatter on the expected code.
