Decentralize completed output even when its not completed

[hemz10]

Overview

If for some reason decentralization fails and if we try to run again we immediately get the output that decentralization is completed.

Steps to Reproduce

Steps to reproduce the behavior:

1. dive chain icon
2. dive chain icon decentralize -p gochain -k keystores/keystore.json -n 0x3 -e http://172.16.0.8:9080/api/v3/icon_dex -s invalid service name
3. dive chain icon decentralize -p gochain -k keystores/keystore.json -n 0x3 -e http://172.16.0.8:9080/api/v3/icon_dex -s icon-node-0xacbc4e
4. Observe it says Decentralization is completed.

Expected Behavior

Decentralization should start from beginning and decentralization completed output should be displayed only when it is really completed.
