Recent OPR calculations sometimes 0.

[DrewWing]

Describe the bug
Some teams' recent OPR calculated as 0 for lower amounts of days than 30.

To Reproduce
Steps to reproduce the behavior:

1. Run statistics calculations on a team that hasn't played within NUMBER_OF_DAYS_FOR_RECENT_OPR days
2. Push to Sheets or otherwise export OPR data
3. See that recent OPR calculations are 0

Expected behavior
Recent OPR calculation

1. Keeps increasing recent number of days until an event is found, or
2. Uses last event.
   It should also log a warning to errors.log.

Actual behavior
Since the team hasn't played within the constant NUMBER_OF_DAYS_FOR_RECENT_OPR amount of days, the script runs into an error and sets all statistics for that team to be 0.

System:

• All OS platforms
• All browsers
• Main v49.0 Alpha
