Q# namespaces with the same fully-qualified name as a callable or type produce invalid C# code

[bamarsha]

This program is accepted by the Q# compiler:

namespace Foo {
    function Bar() : Unit { }
}

namespace Foo.Bar {
    function Hello() : Unit { }
}

But it produces this C# compile error:

obj\qsharp\src\Program.g.cs(26,26): error CS0101: The namespace "Foo" already contains a definition for "Bar".

This is very closely relate to this one I believe: #46
It may make sense to track the two together.

[bamarsha]

Yes, they're both related to flat Q# namespaces working incorrectly with nested C# namespaces. My instinct is to keep both of them separate since they have different error messages, but I'm OK with it if you want to combine them.

After reviewing this along with the work for #346 , it seems like it makes more sense to block this in the Q# compiler than try to handle it properly. I'm going to move this issue over to the compiler repo.

Closing in favor of compiler repo issue.
