Children Tracking Issue: Multiple references to the same child overwrite each other

[jabdoa2]

This bug has existed for a long time in wave. In some cases wave might add a hash annotation even though a child is still missing.

Wave tracks its children (configmaps and secrets) in a map. If the same child is used in two places the second occurance overwrites the first one. This can make a required child optional. It might also in some cases exclude used keys from the hash.
