fix: Verify home key exists when querying for matchup data

[jelias2]

• I discovered a bug which caused the intialization of the league object to crash.
• I believe this occurred because in my league we have an odd number of teams which results in one matchup each week having only one team and that team always appears to be the away team,

When creating the outcomes object the code looks for the home and away keys even though they may not exist in the matchup object in a league with an odd number of teams.

This PR adds a check to ensure the home key exists prior to lookup to avoid a crash.

Here was the error I received, prior to implementing the fix.

python3 main.py                                                                                                                                                                              ─╯

S/o to @wowcanubelieveit for providing the league with odd teams and the crash scenario, and for rapping dreams and nightmares to motivate me while debugging
