This fixes two related problems.
First, according to the spec the shutdown message should have no parameters.
rust-analyzer and erlang-language-platform respond with an "unable to deserialized error" when given an empty map instead. e.g.
LSP :: (error Failed to deserialize shutdown: invalid type: map, expected unit; {})
But this was hidden because the condition case swallows the error info and always reports timeout.
A genuine timeout is now reported as
LSP :: (error Timeout while waiting for response. Method: shutdown)
