Import file hint doesn't work as expected

Import file hint pops up even though a file is properly imported. The problem occurs when I use multiple inheritances and I define a structure in the root contract. For instance:

contract A {
  struct MyStruct
}

import "A.sol";

contract B is A {
}

import "B.sol";

contract C is B {
   MyStruct A; //My struct is correctly imported as its part of B
}

In contract C MyStruct is correctly imported. Even though plugin prompts me to import A contract. Moreover, even if I do that, it keeps prompting me about that.

Thanks @0v1se for fixing.

I added one more test I really like how the issue translates into a test:

@SerCeMan ok, I’ll fix it in some days if you don’t mind
