Throw error when currently, there are no active wallets in the network
and when the user requested redemption for all active wallets in the
network using the same Bitcoin address - in that case, a user should use
another Bitcoin address.

There is always only one "active" wallet in the system. This is the one
that accepts new deposits. What we are talking about here are "live"
wallets that are operable from the Bridge's standpoint. Here we rename
the `activeWalletsCounter` variable to `liveWalletsCounter` and adjust
the nomenclature everywherre accordingly.
