Optimize team_get_fixture()

Browse Source 
When searching for a team's next fixture, only search in leagues that the team
is actually in.  This improves performance a lot in countries with many leagues.
I see about a 7x speed up simulating the first 6 weeks of English leagues using
billys_boots 2019/2020 definitions from the forums.
