Clean date function for TargetExtra

[brendanrmills]

I noticed that if you wanted to save the contents of an alert into a bunch of TargetExtra objects to keep track of the parameters, the TargetExtra class would throw a RuntimeWarning

/home/bmills/bmillsWork/tom_test/new_venv/lib/python3.9/site-packages/django/db/models/fields/__init__.py:1534: RuntimeWarning:
DateTimeField TargetExtra.time_value received a naive datetime (2018-07-07 08:25:56.001000) while time zone support is active.
This was because TargetExtra casts the date as a datetime but it is common for django projects to require timezone information. This was fixed by adding a clean_date() method that just appends ' UTC' to the end of the firstdate and lastdate. I also wrote a small testing function to verify this.

Hi @brendanrmills -- many thanks for checking, and for the update!

Actually, it's been a while I did not run a query -- but the team should resume soon on using the module for follow-up, so we will inspect carefully and add new features that we recently discussed.

Typo: there should not be comma here

@brendanrmills and @JulienPeloton Is this PR still live?

I would be tempted to merge the changes. However the CI is failing, and the fail happens early, at the metadata generation for the package:

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

I would log the error, and investigate in a separate branch.
