Lisk core upgrade to latest version using Lisk commander failed - Closes #4037

[ManuGowda]

What was the problem?

Commands lisk core install and upgrade failed due to missing default release URL

How did I solve it?

Handled default release URL for install and upgrade

How to manually test it?

cd commander;
npm run build;
./bin/run core:install --network=testnet --no-snapshot --lisk-version=2.0.0-rc.0 lisk-testnet
./bin/run core:status lisk-testnet
./bin/run core:stop lisk-testnet
./bin/run core:start lisk-testnet
./bin/run core:restart lisk-testnet
./bin/run core:upgrade --lisk-version=2.0.1-rc.0 lisk-testnet
./bin/run core:status
./bin/run core:logs lisk-testnet

@ManuGowda the following fails without any clear error message:

lisk@ams3-francois-commander-01:~$ ~/lisk/bin/lisk core:install --network=testnet --no-snapshot foo
  ❯ Install Lisk Core testnet instance as foo
    ✖ Prepare Install Options
      → Cannot read property '0' of null
      Validate root user, flags, prerequisites
      Download Lisk Core Release and Blockchain Snapshot
      Extract Lisk Core
      Register Lisk Core
      Create Database and restore Lisk Blockchain Snapshot
 ›   Error: {"context":{}}

Those work as expected however:

~/lisk/bin/lisk core:install --network=testnet --no-snapshot --lisk-version=2.0.0-rc.0 bar
~/lisk/bin/lisk core:upgrade bar

~/lisk/bin/lisk core:install --network=testnet --no-snapshot --lisk-version=2.0.0-rc.0 baz
~/lisk/bin/lisk core:upgrade --lisk-version=2.0.1-rc.0 baz

Same for ./bin/run core:install --network=testnet lisk-testnet
