Remove always-NULL $singleRecord variable

[eileenmcnaughton]

Overview

Remove always-NULL $singleRecord variable

Before

Per #25517 $singleRecord is always NULL so

1. the removed condition renders to NULL != 'new & is always TRUE
2. the value passed to the second function is always NULL, which is the default for the parameter so we don't pass it

After

extraneous usage removed

Technical Details

This can be merged separately from #25517 as that PR 'makes the case' but is not required for this to be TRUE. There is other follow on cleanup to do on other parameters so the variables will get flushed out then if need be
