fix (recipe): Don't set creation watch on lock predecessor node
Using exists will register a creation, as well as update and deletion
watch on the given node. This introduces a race, where the predecessor
node can get deleted between the call to getChildren() and exists().
If that happens, the exists() sets a create watch on a node that will
never be created, leaks a create watch.
