Code generation failure when mapping Q# namespaces to C# namespaces

[vadym-kl]

Describe the bug

Consider two files A.B.qs and B.qs with namespaces A.B and B and operation Foo defined in B.qs. Fully qualified call B.Foo() in A.B.qs is valid Q# code that leads to invalid C# code,
because in C# B.Foo() is equivalent to A.B.Foo() in this case.

To Reproduce

First file:

namespace Buggy {

    operation Foo() : Unit is Adj {
    }
}

Second file:

namespace BuggyBuggy.Buggy {

    operation Foo2 () : Unit {
        Buggy.Foo();
    }   
}

Expected behavior

Successful compilation of Q# program.

Actual behavior

C# compilation error

 error CS0234: The type or namespace name 'Foo' does not exist in the namespace 'BuggyBuggy.Buggy' (are you missing an assembly reference?)

System information

• OS: Windows

Additional context
Not critical, the simple workaround is to avoid the situation by naming namespaces differently.
