base-foc: fix 'Genode::parent_cap()'

Browse Source 
Replacing the local name of a capability index object which exists in the
capability map can destroy the AVL tree order of the capability map. With
this patch the outdated object gets removed from the map and a new object
gets inserted afterwards.

Fixes #435.
