feat(LSP): Override pretty flag for Mypy

As the `--pretty` flat for Mypy provides nicer output, the soft word
wrap it uses makes editors receive part of the message.  Hence the
setting has to be overridden inside editors (the flag is kept on
because invoking Mypy from terminal benefits from the extra output
information).
