LSP does not like anything 'above' `#lang`

[Release-Candidate]

Anything before #lang in a file causes an exception. It does not matter whether there is a comment, an empty line,... -

Example - adding an empty line (which isn't visible in the rendered Markdown) above #lang:

#lang racket

Exception:

Caught exn in request "textDocument/documentSymbol"
rest: contract violation
  expected: (and/c list? (not/c empty?))
  given: #<void>

This should be fixed, @Release-Candidate would you like to check it?

Yes, thanks. This works for me with the latest LSP version.
