When a new namespace is created, connections are not set up by default. The user has to manually set them up.
If the user navigates to Wrangler from Pipeline Studio (by clicking [Wrangle] in the Wrangler plugin properties view, the system needs to detect if any connections are available, and display the root to the user.
- By default, the first connection available in the connection menu, should be displayed.
- If no connections are established the connection menu is displayed and themessage is changed to "No connections are available you should try to...."
- Remove the header: it is redundant
