Merge bitcoin-core/gui#803: test: Set organization name

0dcbad3 qt, test: Clean settings after tests (Hennadii Stepanov)
49cf635 qt, test: Set organization name (Hennadii Stepanov)

Pull request description:

  From Qt [docs](https://doc.qt.io/qt-5/qsettings.html#QSettings-4):

  > If [`QCoreApplication::setOrganizationName()`](https://doc.qt.io/qt-5/qcoreapplication.html#organizationName-prop) and [`QCoreApplication::setApplicationName()`](https://doc.qt.io/qt-5/qcoreapplication.html#applicationName-prop) has not been previously called, the `QSettings` object will not be able to read or write any settings, and [`status()`](https://doc.qt.io/qt-5/qsettings.html#status) will return [`AccessError`](https://doc.qt.io/qt-5/qsettings.html#Status-enum).

  Fixes bitcoin-core/gui#799.
