Duplication of container icons when opening the browser

[Rdornier]

Sometimes, I noticed that when you open the OMERO browser, containers icons are duplicated at the bottom of the browser.
They are not selectable but still present when switching group/users.

By expending any container, they disappear.

This bug doesn't always occur when you open the browser ; it only occurs at the very first opening of an OMERO browser and only if the connection was initiated via manage server connections menu. To reproduce it :

• Disconnect from the current server
• Open the manage server connections menu
• Connect to the server from this menu
• Wait until the connection is active (green dot)
• Open the corresponding browser
