Enable remaining failing tests

These are basically the tests that are failing right now and are marked as ignored. 
However they will fail in TravisCI and thus break the future contributions to the plugin so they are disabled in the current ``` master ```.
As such I've enabled them here so we can keep a track of them.

Possible contributors

If you are looking to contribute to the plugin, you might want to pick up these tests and solve one of them. You'd have my eternal gratitude.
Thank you.


**Please DO NOT merge this until everything is fixed.**
