The user branch of a user was always advertised to that user even if
READ permissions had been denied or blocked.
Doing a visibility check for the user branches means that by default
they are now no longer visible to the owning users, but the default
will be changed by a follow-up change. The next change implements a
parameter variable for ref patterns that can be expanded to the
sharded account ID. This new parameter variable will then be used to
assign the default permissions for the user branches.
Leave an exception for change edit refs since the inline edit feature
depends on the change edit refs being always visible to the owning
user.
