elc_naviframe: Remove default label when necessary

When using a Naviframe inside of another Naviframe the default label
stack can become corrupted, i.e. the items from both naviframes can get
intermixed (as in the case of wifi-efl-ug), causing navigation issues.
Limiting the default label stack to one item per Naviframe helps solve
this issue.
