Fix VARCHAR vs TIME type mismatch in med_logs queries (#15)

Browse Source 
The medication_schedules.adjusted_time column is a TIME type, but
med_logs.scheduled_time is VARCHAR. When adjusted_time values were
passed into queries against med_logs, PostgreSQL rejected the
comparison. Add _normalize_time() to convert datetime.time objects
to "HH:MM" strings at the entry points of should_send_nag,
record_nag_sent, and mark_med_taken.
