Merge pull request #517 from keep-network/repair-lcl-initialize-script

Repair lcl-initialize script

The sortition pool creation logic in lcl-initialize.js script, didn't consider a case when getSortitionPool 
method returned a zero address. 

It is a workaround for ethereum/go-ethereum#21083 - instead of failing,
contract call returns address 0x0. Once we are able to update to the most recent abigen 
see keep-network/keep-common#45), the additional case for 0x0 address 
should be removed.
