Open namespace issues

Few issues I’ve come across repeatedly:

1. Rider sometimes adds the open above the first line (above namespace/module), not sure why
2. Rider cannot deal very well with multiple namespaces in the same file, it gets confused where to put the open causing the open to have no effect on the code you’re writing.
3. Rider does not take AutoOpen into account when it opens from a function suggestion, causing the auto opened module to be added unnecessarily into the completion too.

@NinoFloris Yes, this case wasn’t implemented yet. Thanks for repro!

So quick fix ignores the parent class and imports just the namespace which is wrong in its own way without symbol fixup at the import site, while code completion tries to import the parent class like I said.

it’s super simple

namespace ReproCs
{
    public class Foo
    {
        public class Bar
        {
        }
    } 
}

module ReproFs

let bar() = Bar // try either quick fix or code completion for the fireworks.
