Group manual address : confusing and useless "Save" button

Edit a group manual address :

• Add a name

Say you want to save.

If you click on "Update group", you address is lost. If you click on "Save", then update group, your adresse is also lost.

We need :

• If there is a manual address, the detail section is opened
• Remove the Save button, we only need one button !
• Rename the "Clear" button to "Clear address" : less confusing
• When saving, display errors if there is errors !
