XEP-0203: Prevent naïve datetime from being passed

Browse Source 
The specification says “The format MUST adhere to the dateTime format
specified in XEP-0082 and MUST be expressed in UTC.”

We now respect this requirement, by rejecting naïve datetimes with a
ValueError exception, and converting the passed datetime to UTC.

Fixes #3471.
