Pull request description:

  Closes #16820. The wallet [name escaping issue](https://github.com/bitcoin/bitcoin/pull/15450#pullrequestreview-282297760) in that issue predates #15450 and is fixed by #16826.

  - [x]  rename encrypt() to encryptWallet(), and blank() to makeBlankWallet() // EDIT: updated to
          isEncryptWalletChecked()
          isDisablePrivateKeysChecked()
          isMakeBlankWalletChecked()
  - [x]  fix naming of askPasshprase() to askPassphrase()
  - [x]  fix passphrase labels and tooltip in createwalletdialog.ui and askpassphrasedialog.ui
  - [x]  fix grammar of labels in askpassphrase dialog and WalletController::closeWallet
  - [x]  fix autofocus in CreateWalletActivity::askPassphrase()

  Squashed down to three commits.

  Reviewers, to test manually: build, launch the gui wallet, and look at labels/tooltips/focus with the create wallet, encrypt wallet, change password, and close wallet commands.
