Autocomplete for `end` does not respect multiple cursors

[ghostnaps]

Repro steps:

1. Create 2 or more cursors
2. Write out some code that would normally produce end completion
3. Press enter and notice that only the first cursor receives end completion

Hopefully this is a quick fix as this is not something I would commonly run into
