Change root folder/reset URL name hides depending channels without warning, URL editable by default

1) Start project created by archetype
2) Log in on CMS ago to Content/Documents
3) Open the context menu for the myhippoproject and choose Rename folder...
Expected: URL name is read-only and has a 'Edit' button

Actual: URL is editable with 'Reset' option. Clicking Reset and OK results in error 'No name is changed'
Note that for non-root folders the URL is read-only by default

If you change the root folder URL name any channels related to the folder are no longer available. Would be nice if a warning was shown when renaming the URL.
