[GSK-1296 Change the starting page of a project

[henchaves]

Description

This PR aims to change the default page the user will be redirected to after opening or creating a new project.
The default tab changed from "Catalog" to "Testing".
Also, a code snippet was added to this Testing tab. So that the user can automatically upload the demo artefacts, a test suite and then interact with the other functionalities.
Finally, some bugs were fixed related to refreshing/reloading tabs after uploading objects.
