Pulling performance data for players without any throws an error

[colmquinn]

Where there is no performance data for a player (e.g. https://www.transfermarkt.com/carl-bacon/leistungsdaten/spieler/775809) the tm_pull() will throw an error as there is no table. Not that critical as they aren't very interesting players anyway, and I handle it by using a try except clause when looping through and throwing any errors into a list to check later.
