Fix non-regional/district/dcmp competition weeks and sorting

[democat3457]

Current Behavior Non-regional/district/dcmp competitions, or just "special events," are given a value of Week 1 and sorted at the beginning of the team event list, even when the competition may not have occurred during Week 1.

Cause Special events get the week deserialized into the int default value of 0 when the week key actually returns null. Also, the code doesn't check for event_type or event_type_string, which will also allow checks on the type of the event to determine whether week value should be ignored.

Just as clarification:

• Values from the api are returned as index 0, the bot responds with index 1 to the end user,
• The events are not sorted (by the bot)

Probable Fix:

• Create a static method or helper class to automatically check multiple values and return desired data.

While I'm tempted to update the schema POJOs, it would break lots of code not checking for null values as currently the schema uses primitive data types. could be good for a later date though.
