YELLOW_STAR and STARRED labels are duplicated with same amount of emails

[martgil]

It was observed that the labels YELLOW_STAR and STARRED seem to be duplicates of each other, as the emails under each label are essentially the same.

I believe this redundancy can be avoided by using only one of them, with STARRED being the preferable choice.
