Deleting buffer at TermClose event doesn't trigger WinEnter/BufEnter events

[jceb]

Describe the bug
I maintain the blinds.nvim plugin that changes the background color of windows that are currently not selected. The functionality relies on WinEnter and BufEnter events fire. With Neoterm I noticed that the events aren't triggerd when I close a terminal.
The reason for this appears to be that vim doesn't fire WinEnter and BufEnter events when a buffer is deleted in the TermClose event.

For debugging purposes I disabled the TermClose auto command. This solved the issue. Furthermore, I ran an explicit :bw! on a newly created neoterm window and it still called the neoterm#destroy function through the job.on_exit handler - this handler doesn't cause the issue that TermClose does (it might also be a neovim bug). My impression is that the TermClose auto command can be deleted because the underlying functionality of cleaning up the terminal buffer is already triggered through the job.on_exit handler.

To Reproduce
Steps to reproduce the behavior:

1. Open neovim (window 1 contains the empty buffer)
2. Create a second window :new
3. Opened a neoterm with :T bash in window 2
4. Display all auto commands set verbose=9
5. exit neoterm ''
6. See error, no WinEnter or BufEnter auto command ist triggerd

Expected behavior
Window 1 should have the background color of the active window.

Hi there, first of all, thanks for the very detailed issue. <3

My impression is that the TermClose auto command can be deleted because the underlying functionality of cleaning up the terminal buffer is already triggered through the job.on_exit handler.

Yeah, I agree. I did a quick test and without the TermClose action the BufEnter worked and the destruction of the neoterm object seem to work properly. 🎉
