[Cloud Functions] Passlist not respected by Cloud Functions

[gino-m]

Import and export functions check roles in survey, but not passlist.

Updating the user profile only allows authenticated users to update their existing own profile, so it's less of an issue.

Neither issue is critical, but should be fixed.

@rfontanarosa FYI

i would like to rediscuss this issue @gino-m

@rfontanarosa I believe this obsolete since all functions are gated on survey ACLs. Please cmiiw.
