get_team_info() no longer works for counterstrike/dota teams.

[Kushtrim-88]

The default usage of the method :

team_details = counterstrike_obj.get_team_info('Team Liquid',True)

throws out this error:

Traceback (most recent call last):
File "teams.py", line 5, in
team_details = counterstrike_obj.get_team_info('Team Liquid',True)
File "C:\Users\WDAGUtilityAccount\AppData\Local\Programs\Python\Python38-32\lib\site-packages\liquipediapy\counterstrike.py", line 104, in get_team_info
team['team_roster'] = team_object.get_team_roster(soup)
File "C:\Users\WDAGUtilityAccount\AppData\Local\Programs\Python\Python38-32\lib\site-packages\liquipediapy\counterstrike_modules\team.py", line 65, in get_team_roster
team_roster = roster_cards[0]
IndexError: list index out of range

Same thing seems to happen with DOTA 2 teams,

Error:

Traceback (most recent call last):
File "teams.py", line 5, in
team_details = dota_obj.get_team_info('Hippomaniacs',True)
File "C:\Users\WDAGUtilityAccount\AppData\Local\Programs\Python\Python38-32\lib\site-packages\liquipediapy\dota.py", line 91, in get_team_info
team['results'] = team_object.get_team_achivements(soup)
File "C:\Users\WDAGUtilityAccount\AppData\Local\Programs\Python\Python38-32\lib\site-packages\liquipediapy\dota_modules\team.py", line 108, in get_team_achivements
indexes = rows[0]
