newly created encounters do not always get indexed

[naknomum]

Expected behavior
create a new encounter, it is immediately indexed for searching

Current behavior
sometimes a new encounter is not immediately in the index

Notes
there is problematic code in enc.opensearchIndexDeep() which tries to remedy this by using origEnc -- and it needs to be removed.

for example: create a new Encounter with no images. this causes postStore() to execute, and then opensearchIndexDeep()... however the encounter is not available in db yet for some reason; thus the index fails. [assuming the origEnc problematic code is removed.]
