setTranslation w/ merge flag is misleading. It does an extend rather than a proper merge.

Current behavior
setTranslation with merge set, really does and extend (Object.assign) under the covers. A True merge would be more useful for those building applications where we need to override translations values from a base translation file.

Expected/desired behavior
setTranslation with merge set should perform a proper merge (like lodash merge)
