wallet: fix scanning progress calculation for single block range

Browse Source 
If the blockchain is rescanned for a single block (i.e. start and stop hashes
are equal, and with that also the estimated verification progress) the progress
calculation could lead to a NaN value caused by a division by zero, resulting in
an invalid JSON result for the getwalletinfo RPC.  Fixed by setting the progress
to zero in that special case.
