Missing "staking(Bonded)" event associated to "staking(rebond)"

[TheGoldenEye]

After executing a "staking(rebond)" extrinsic I miss the associated "staking(Bonded)" event.
Unfortunately it is not possible to track bonding/unbonding/rebonding this way.
I think "staking(Bonded)" should be triggered in response to "staking(rebond)", possibly a new event as well.

Thanks for the report! I opened a PR to fix this.
