There's a few small issues left over from #15450:

* [Focusing](https://github.com/bitcoin/bitcoin/pull/15450#pullrequestreview-282297760) on the `Encrypt Wallet` dialog after clicking `Create Wallet`.
> ```cpp
> m_passphrase_dialog->setWindowModality(Qt::ApplicationModal); 
> m_passphrase_dialog->show();
> ```

* Wallet [name escaping issue](https://github.com/bitcoin/bitcoin/pull/15450#pullrequestreview-282297760):
> This is at least one inconsistency where if you create a wallet with a HTML escaped character in the name, i.e Alice & Bob, then the & will not be shown in some menus / dialogs.

* Nits from this [review](https://github.com/bitcoin/bitcoin/pull/15450#pullrequestreview-284450044).
