[console] fix bug of old persisted state for a network crashing the view

[kasparkallas]

What?

Users can set preferences for test networks for themselves. Those preferences are stored in the local state. When a network is removed and the user had a preference for that network then the app crashes. The fix is to clear the local state.

Why?

It's not a good look and it will surface again in the future. The fix is very destructive for the end-user if they have other local state (like the address book).

How?

• soft delete the networks instead
• add some error boundaries (even if there's a error in some of the components, it shouldn't bring the whole app down)
• remove the expectation that all the networks exist that are stored in the local state
