We should not check if caller of "respond" is a participant

[volovyks]

We should not check if the caller of the “respond” function is a participant.
We agreed that we would use a locked contract and move from v1.mpc.near to v2.mpc.near in case of an upgrade. We plan to index both v1 and v2, but the participant list will be updated only on the latest contract.

I do not see any security risks in this, since we are checking that the provided signature is valid.
