wsPath that you are using potentially may be not a project path but a project item path. For example project path may be /projects/p1 and wsPath will be /projects/p1/pom.xml

[dkulieshov]

I think we should use something like org.eclipse.che.api.project.server.ProjectManager#getClosest to get real project and then get its workspace path. What do you think?

@dkuleshov thank you for pointing this out! I've updated the PR.

During testing this PR with QA team it's appeared that 30 sec. isn't enough to initialize C# LS including restoring project's dependencies.
@SkorikSergey I've increased the timeout for initializing LS. Could you please check it again?

Selenium tests execution on Eclipse Che Multiuser on OCP (https://ci.codenvycorp.com/job/che-pullrequests-test-ocp/472/) doesn't show any regression against this Pull Request.
