Comment (by arlolra):

 If `sendAnswer()` returns an error, `pc.Destroy()` is called and the token
 is returned,
 https://github.com/keroserene/snowflake/blob/master/proxy-
 go/snowflake.go#L370

 However, `makePeerConnectionFromOffer()` will have now set a timeout that
 will also call `pc.Destroy()`,
 https://github.com/keroserene/snowflake/blob/master/proxy-
 go/snowflake.go#L345

 This patch moves the timeout to after `sendAnswer` returns,
 https://github.com/keroserene/snowflake/commit/2e4383434f33a4f8e801974bbe70d8a4568b3d93
