Sync get, getAll, batchGet, and search getInternal behavior

[jsdonn]

Is your feature request related to a problem? Please describe.

PR#132 changes the intended behavior of get() when parameter aspectNames is empty. Instead of throwing a 404, it will return VALUE with no aspects. To accomplish this behavior, getInternalNonEmpty call was changed to getInternal. We need to evaluate this behavior with getAll(), batchGet(), and search() methods to make sure they are aligned with get()'s new behavior.

Describe the solution you'd like

Double check and update calls to getInternalNonEmpty if needed to match with new get() behavior.
