Wallet name allows trailing spaces

[MikeO7]

The wallet name allows trailing spaces which can make it difficult to remove the wallet. The trailing space needs to be included in the removal process or it will not match

Steps:

1. create a new wallet with a trailing space: ADA Wallet_
2. Attempt to remove the wallet using: ADA Wallet
