JENKINS-37104# Matrix project handling (#412)

* JENKINS-37104# Matrix project handling

- Bare minimum support for Matrix project. Ensures it doesn't break.
- For matrix project, self href points to classic URL path ("/job/:name")
- Adds hudson.matrix.MatrixProject capability
- UI to check hudson.matrix.MatrixProject capability and if present create a link using returned self href,
  so that when user clicks on it, he gets redirected to classic Matrix job page.

* Reverting removal of matrix project test dependency, favorite tests fail as Favorite plugin idepends on matrix project plugin and has reference to MatrixConfiguration.
