[brainwo]

Description

import completion prints the prefix twice
Some examples of the problem:

import 'package:package:vm_service/'
import 'package:vm_service/package:vm_service/vm_service.dart'

Steps to Reproduce

Steps to reproduce the behavior:

1. Type import 'package:ffi/
2. Let the autocompletion window open
3. Select package:ffi/ffi.dart from the completion
4. Got this import 'package:ffi/package:ffi/ffi.dart'

Expected behavior
The reproducible steps should produce import 'package:ffi/ffi.dart'.
Just like the VS Code extension or any other Coc extensions.
