Title: Clean up some ember-metal chains code

1. The first change removes a weird instance of
improperly removing nodes from an array which
would break in case there’s every a time that
a node appears in the array more than once
(but I’m pretty certain this is never the case) 2. Removed unnecessary
.length check of
(str && str.length > 0)
