Its about the new LSP/Textmate UI integration and It is about error handling,
because the behaviour is not very nice.
Steps to reproduce:
* Open a project (Only to initialize the editor and the specific options)
* Open Tools -> Options -> Editor -> Language Servers
* Click on Add
* Leave everything empty
* Click on on
* Liune will be added with default icon and the placeholder word "files"
* Hit apply in the options window.
* See error message thrown.

So I prefer to add validation. Make the name not optional. It should have a
name. thats all. Icon also but you add the default one, that is okish. Maybe
the lexer file need also be required, I think this is why the error is thrown.
