Easy to accidentally add imports for same component

[brunnerh]

Describe the bug
If i have a file re-exporting components and then import from that, the import to the original file gets inserted in the script automatically when auto-completing the component name and using the first result.

To Reproduce

Example:

// Barrel file: /utility/index.ts
import Button from './button.svelte';
import TextField from './text-field.svelte';
import Dialog from './dialog.svelte';
...

export {
	Button,
	TextField,
	Dialog,
	...
}

<!-- Component /components/edit-dialog.svelte -->
<script type="text/typescript">
	import { TextField, Button, Dialog } from "../utility";
	import Dialog from "../utility/dialog.svelte"; // Gets inserted on auto-completing to Dialog tag in HTML below
</script>

<Dialog>...

Expected behavior
The existing named import is recognized and no additional import is added.

Screenshots

There are two Dialog entries, the first one adds the redundant import, the other one is for the existing named import. Ideally the first suggestion would not appear if the named import is already there.

System (please complete the following information):

• OS: Windows 10, 64bit
• IDE: VSCode
• Plugin/Package: Svelte for VSCode

(I only noticed that both suggestions exist at the same time just now, so this might not necessarily be considered a bug.)

All Svelte component under the hood are postfixed with __SvelteComponent so that you can import something called Component into Component.svelte and not have name clashes from typescript. The problem now likely is that we leave module resolution to typescript, which then sees that X__SvelteComponent is not imported yet. A fix would be to sort the results differently or to filter out the completion.
