Fix looking for objects on root path

The current code would not remove the "/" for the root
path causing a subtree or other call with path being
"/" to miss any object exposed on "/". Fix this
so that "/" is removed when it is the only character.

Tested-by: Phosphor-pid-control stopped throwing when
looking for object managers.
