Running PackerCompile loads another instance of event lazy-loaded plugins if events are fired again.

[Pranav-Badrinathan]

• nvim --version: v0.6.0
• git --version: 2.31.1.windows.1
• Operating system/version: Windows 11
• Terminal name/version: Windows Terminal

Steps to reproduce

This happened with cmp-path and cmp-cmdline, both of which were loading on the CmdlineEnter event. To reproduce my exact case:

1. Install nvim-cmp and cmp-cmdline and set cmp-cmdline to load on CmdlineEnter.
2. Open any file and start typing the :colorscheme command on the command line. You should only see one suggestion:
3. Run :PackerCompile or :PackerSync.
4. Retry typing :colorscheme and you should see not one, but 2 suggestions:
   
5. Repeating step 3 and step 4 should increase results by 1 each time.

Actual behaviour

The command :PackerCompile seems to mess with event loaded plugins, and loads another new instance each time that event fires after compiling.

Expected behaviour

It should remember the active events and not launch another instance again, or just reload all plugins on compile, stopping the previous instance beforehand.

Plugin specification file(s)

Post or link your plugin specification files here, if you aren't able to provide a minimal reproducer

packer log file

Post the contents of ~/.cache/nvim/packer.nvim.log here It seems that the log file I have is not the most recent and displays some errors that were due to configuring stuff previously. Anyways, if you still need it: https://pastebin.com/218vfDxE

packer compiled file

Post the contents of packer_compiled.lua here

Can confirm this, most noticeable with nvim-cmp sometimes I got 3 line of the same completion
