View is not changed after the seal request. View is changed after the block generation request.
What do you think about "Seal request for an old view"?

If generating a block takes too much time, the view could be changed before the miner module requests the signature. If the Tendermint module receives a signature request of an old view, it should ignore the message. Before this commit, the Tendermint module was crashing when it gets a signature request from an old view.

If generating a block takes too much time, the view could be changed
before the miner module requests the signature. If the Tendermint
module receives a signature request of an old view, it should ignore
the message. Before this commit, the Tendermint module was
crashing when it gets a signature request from an old view.
It fixes #1805.
