Apply pyformat to WebSocket layout tests

Applied pyformat to WebSocket layout tests to bring them closer to pep8
compliance.

Command-line used was

pyformat -s4 -r -i --force_quote_type single --ignore 'E501' .

It doesn't seem to be possible to completely prevent pyformat from
wrapping long lines, so some changes were reverted by hand.
