Don't add already known documents to the misc files project

[davidwengier]

Noticed in the logs that we were double-compiling files, and it was causing issues in my "self versioned documents" branch. Separated out of that to make it easier to review.

RCA is because we now share a project manager across VS and LSP server, so we get real project information much sooner than before, which beats file watchers etc.

Isn't this basically the same as the below?

Suggested change

	var potentialProjects = _projectManager.FindPotentialProjects(textDocumentPath);
	foreach (var project in potentialProjects)
	{
	if (project.DocumentFilePaths.Contains(textDocumentPath, FilePathComparer.Instance))
	{
	// Already in a known project, so we don't want it in the misc files project
	_logger.LogDebug($"File {textDocumentPath} is already in {project.Key} so we're not adding it to the miscellaneous files project");
	return;
	}
	}
	if (_projectManager.TryResolveDocumentInAnyProject(textDocumentPath, _logger, out var project)
	{
	// Already in a known project, so we don't want it in the misc files project
	_logger.LogDebug($"File {textDocumentPath} is already in {project.Key} so we're not adding it to the miscellaneous files project");
	return;
	}

lol, it very well could be. That's a little embarassing :D

This isn't quite correct. We don't share a project manager across VS and the LSP server, but we do share project information.
