If not specified by caller, set registration completed to false.
By not setting it to false on all creates, this allows the caller to create a registration completed.
Secondly, and maybe more importantly, we don't know whether this update is actually a create until after we have converted the Registration into an entity, and if we wait until then to set the completed value, we'd have to set it twice, in both the Registration and Entity objects, which seemed not the best.
Set the boolean in the caller provided registration object which will later be used to evaluate that boolean value.
Correct java doc @param (which Intellij considers an error).
Change Registration completed field type from Boolean to primitive boolean.
Makes field management easier. Defaults to false when not set by caller.
