Loosen restrictions before generating tasks.json and launch.json

It is no longer necessary to ensure that the workspace root contains a project.json (or global.json) before offering
to generate tasks.json and launch.json. When launched, OmniSharp should scan for projects and, if any or found, we'll
offer to generate the assets if needed.
