XlrStats: !xlrstats command silently fails on a 1st time seen map

from a support request on the forums: on the log below, a player uses the !xlrstats command right after the bot starts. B3 knows the map name but the is no line in the xlrstatsmap stat table for this map, hence the get_PlayerMaps method is called with None for the map id parameter and fails.
the get_PlayerMaps could check the validity of its mandatory parameter and fails with a debug/error log message.
the Xlrstats plugin could create the map stats table for the current map (if it does not exists in database) at plugin start, hence ensuring any call to method get_MapStats returns a MapStats object with map id
