Description of the change

Adding VIB tests to the OsClass Chart.

Additional information

A Goss test for checking HTTPS connectivity on an alternative port (444) is failing. This is outside of the scope of adding the tests but needs to be fixed. I will create a separate task for it.

@FraPazGal, @joancafom, I've changed the following:

• Simplified selectors, URL's where possible
• Reverted to using the default SSL port as using a non default one breaks the application. I will create a separate task to fix this.
• Added a test for the database name, checking the credentials was not possible as they don't appear in the configuration file.
• Removed wrongly committed Moodle file.
