Auto-import of an item that's already conditionally-imported creates a duplicate import

• given an input like

  #[cfg(feature = "foo")]
  use std::collections::HashMap;
  
  fn bar() -> HashMap {
      todo!()
  }
  

• with foo being an inactive feature cfg in the current RA session
• when using the import assist on HashMap
• a second use std::collections::HashMap; is generated
• which will result in a duplicate import error when the code is compiled with --feature foo

Reproduce the import-assist case in a Rust file using the conditional HashMap import and an inactive feature cfg. Start at the import assist entry point and trace how existing conditional imports are considered; done means invoking the assist does not generate a duplicate import and the example compiles when feature foo is enabled.
