Adding a test in EdenTest to test project update workflow

Addiing a test for editing project. Does the following:

* Logs into eden.
* Goes to the project page.
* Opens the first project.
* Edit it's name.
* Submits and check for confirmation. 
The name of the test case is exactly what you you specify in the test case without any conversion. So, it should be something like,  `Updating a Project should be successful`. It is a minor thing but a good practice to incorporate.
