[console wallet] Custom Base Node - clear

[leet4tari]

Describe the bug
Adding multiple Custom Base Nodes, increases the base node list, but you can only clear/delete one entry (the last base node).

To Reproduce
Run the tari_console_wallet, navigate to the network tab.
Press P to add a base node. Enter base node pub key and address.
Add a second base node. Clear base node by pressing C.
Pressing C again does not remove the first base node added.

Expected behavior
Expected to be able to delete all Custom Base Nodes, not just last and no others.
