Worth noting, I believe there is a potential bug that needs sorting. At the moment when editing setting a wallet is based on credential name and on editing account name we are only editing account name.
This means when editing account at index 0, we end up with 2 accounts with different names with index 0. To overcome this, I am manually removing the 'initial' wallet version, however the 'updated' value is appended to the end of the account list.
Currently index 0 is not deletable, however if this was to be done for an account at another index ie 2, and the wallet list index order was 0,1,3,4,2 and a user was to delete the last element (2), they would never be able to regenerate it.

To fix this we either list accounts ALWAYS in index order OR we set credential/account based on address/account index and not credential name, thus not inserting a new entry to the list each time edit name is done.

Have fixed the potential bug pointed out in above comment with the commit 45dcc2c

Ordering accounts by address index inside useEffect reorders list on account edit. Also a check in place on delete to ensure that the account to delete's address index is accounts length -1. This ensures deletion of last indexed account only.
