Clean up recursive and dead state in redux

[oskarleonard]

Expected behavior

Users should not have dead or recursive state in redux

1. We need to remove redux/blockChainApplications/applications/{network} if the network doesnt exists in redux/settings/customNetworks || src/modules/network/configuration/networks.js
2. We need to loop through each customNetwork in redux/settings/customNetworks and remove any recursion, for example:

 NetworkA {name: 'a', NetworkA: {name: 'a', NetworkA: and so on...} }

Actual behavior

• Playing around with custom network and adding applications might have caused dead and recursive state

Steps to reproduce

Which version(s) does this affect? (Environment, OS, etc...)
