This is some minor refactoring to support the next CL that will enable the EditArgument request (the one that actually edits arguments, not the one that gets the list of arguments) over legacy. It moves some code for sending LSP reverse-requests through the legacy server from test code into the actual server (and fixes that they weren't correctly wrapped in the 'lsp.handle' protocol classes) and updates the tests to use the shared interface ready.
