not assuming settings.ltex exist

[chomosuke]

Sometimes I don't have any settings to pass into lspconfig.ltex.setup {}. Hence client.config.settings.ltex ended up being nil. This causes exceptions.

I did some refactoring so that every time settings.ltex would be initialized to {} before it's indexed.

Hi @chomosuke! Thanks for your PR, I missed the notification, sorry for the late reply...
Thanks for the refactor, I wanted to make this extract a long time ago.

In theory, ~.setting.ltex should contain at least the default settings for the server. So I don't know if it's better to do an initialization to {} or notify the users that they don't have a config. I have to test it but, am I missing something?

Hey @barreiroleo, in my experience, if I don't write out

{
   settings = {
        ltex = {},
    },
}

Then ~.settings.ltex would be nil. And I don't have any setting to put into ltex so i'd rather not write that out. I'm using nvim 7.2 btw :).
