Fix activation queue bug
Fix bug [flagged by @NIC619 and @hwwhww](https://github.com/ethereum/eth2.0-specs/pull/850#issuecomment-485275575) whereby the `activation_epoch` of validators dequeued since the finalized epoch was overwritten.

Cosmetic changes:

1) Remove `activate_validator` (there is no overlap between genesis and non-genesis activations)
2) Improve comments related to activation queue
