Fixes #1762 segfault when miner is interrupted.

Running ./zcash-cli setgenerate false would result in a segfault.
The miner thread's boost::signals2::connection was not disconnected
when the miner thread was interrupted and shutdown.  Subsequently, when
a new block arrived, the UpdateTip callback would still be invoked on
a now invalid object, resulting in a segfault.
