fix(files): ensure BufWinEnter after :edit <dir>

[abeldekat]

• I have read CONTRIBUTING.md
• I have read CODE_OF_CONDUCT.md

Details:

• By default, 'mini.files' replaces 'netrw'. When a directory is opened with :edit <dir>, and the explorer is closed without opening a file, 'mini.files' shows the alternate buffer if present. If there is no alternate buffer, a new buffer is created. Event BufWinEnter needs to fire in order for mini.clue to attach.

Resolve #2466

Thanks for the PR!

I can indeed reproduce the issue, however the solution is not quite right. Usually if there is a problem with some event not triggering, two most probable causes are: 1) it is executed inside an autocommand without nested = true; 2) there is an explicit/intentional 'eventignore'. The first one is the culprit in this case, as nvim_buf_delete() is executed inside a callback (H.track_dir_edit) for BufEnter function. Modifying the autocommand creation to include nested = true fixes the issue here.

Also note, that merging this will have to wait until 0.18.0 release.

Initially I worried that nested would be propagated to the code in MiniFiles.open causing side-effects. I missed that in H.track_dir_edit it is MiniFiles.open itself that is scheduled. Thanks!
