Merge bitcoin-core/gui#627: Apply translator comments to reset option…

…s confirmation dialog

d5c141f qt: apply translator comments to reset options confirmation dialog (Jarol Rodriguez)

Pull request description:

  This is a followup to dashpay#617. Because the strings were being concatenated, we can not apply translator comments to all of the revelant strings. This can be tested by applying the following diff to current master and running `make translate`; then check the resulting diff:

               QMessageBox::Yes | QMessageBox::Cancel, QMessageBox::Cancel);
  ```

  To apply the above translator comments, what we want to do instead is have a variable in which the translatable strings are appended to using the [QString append function](https://doc.qt.io/qt-5/qstring.html#append).

  When you run `make translate` with this PR, you will see the translator comments properly applied, as shown below:
