Remove duplicates names in no-duplicates autofix

[remcohaszing]

Let’s say we have the following content:

import { a, b } from 'module'
import { a, c } from 'module'

The import/no-duplicates rule will report this, then perform the following autofix:

import { a, b, a, c } from 'module'

I would expect it to remove duplicates, so the output would be:

import { a, b, c } from 'module'

In my experience this is common when resolving merge conflicts if two branches added a new member to the import statement. It’s easy to Accept both changes, then let ESLint autofix resolve any issues with the imports. However, afterwards one has to remove the duplicates manually.

That seems like a good approach. One could be renamed ofc, in which case both would need to be kept, but when neither has a rename, or when they both have the same one, the autofix should be collapsing them.
