scouting: Fix timestamp issue during action submission

The newly deployed scouting app was giving users these kinds of
errors:

   Received 500 Internal Server Error: "Failed to add action to
   database: ERROR: null value in column "time_stamp" of relation
   "actions" violates not-null constraint (SQLSTATE 23502)"

The issue was that the database was created with the
`Action.TimeStamp` field. This was the spelling from the action
submission patch I cherry-picked a long time ago. Later, as the action
submission patch made its way onto master, the spelling changed to
`Action.Timestamp`. This means that a database that was already
created cannot be used by both versions of the software.

Since the database already used the `TimeStamp` spelling, I am
changing the code here to match. For next year, we should settle on a
spelling and fix it.
