Sync networks with applications

[oskarleonard]

Expected behavior

1. When deleting a network we also need to delete it from our application state
2. When changing a name of an network we also need to sync that name change in application state
3. Changing the name of a network that is selected the new name should show in selected network

Actual behavior

1. When deleting a network: That network still lingers in the blockchainApplicationState
2. When changing a name of a network: We make a "POST" instead of a "PUT" to our blockchainApplicationState resulting in duplicated applications where just the name/key is changed.
3. Changing the name of a network results in a blank name as selected

Steps to reproduce

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