Header Count only works for users with firstname + lastname

[joseph-mccombs]

The count for the header drop down only correctly counts the number of surveys for users that have a firstname and lastname attached to their user object. The countService parse cloud function relies on these to query the surveyingUser field in the SurveyData which is populated with firstname + lastname. Legacy Users do not always have a firstname and lastname, so their counts will not be accurate when viewing the header count. We need to attach the user object to SurveyData to ensure we get accurate counts for all users.
