msg.mentionSelf() returns false when a robot is mentioned via its alias

[phoenixgao]

I'm not sure I should report it here or in the wechaty-puppet repository as I don't have a token to try other protocal.

I tracked down to wechaty/wechaty-puppet's async contactSearch() function which can't find the contact data if my bot has its alias in a room, and results in an empty mentionList: [] and failed to return correct mentionSelf() result.

My wechaty-puppet version is 1.7.6
