Failed to load hook pylsp_lint: No such file or directory: flake8_lint.py in run_flake8

At first I thought this was #369 until I realized it's in a different file (plus I tried manually applying the fix that was made for it, and it didn't resolve the issue).

I'm trying to get pylsp working with nvim-lspconfig in neovim. If I just use default settings, something seems to work, but as soon as I try configuring pylsp, I get errors like this:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Here's the config I'm using in NeoVim:

-- Setup language servers.
local lspconfig = require('lspconfig')
lspconfig.pylsp.setup {
    settings = {
        pylsp = {
            plugins = {
                autopep8 = {
                    enabled = true
                },
                flake8 = {
                    enabled = true
                },
                pylint = {
                    enabled = true,
                    executable = "/usr/bin/pylint"
                }
            }
        }
    }
}

Hey @Magicrafter13, thanks for reporting. I think this is a duplicate of issue #406, so I'm going to close it as such.

We'll try to fix in our next version (1.8.0).
