fix: stop auto removing peers

[Jasonvdb]

Description

removeUnusedPeers was added a few years back to avoid connecting to peers that wallet did not have a channel with or was not a Blocktank node. On restore this was being triggered before syncing channels with redux state so it was removing peers before realising there was actually an active channel.

I think auto dropping peers might be a bit premature of an optimisation so I moved it to a manual button for now. A user might have the intention of adding a peer and opening a channel with that peer at a later stage and with this method the peer would be removed on each start up.

QA Notes

After adding an external peer, restore from remote backup and peer should still be there. Or if there was a channel from another LSP it should still be usable.
