fix(History): Deep copy QByteArrays from SQL selects

We already deep copy all other data types. Especially with Qt types like
QByteArray, having a deep copy to start is important since it shallow
copies on any subsequent copy, so the callback provider only gets a
shallow copy in the QByteArray of the temporary data from SQLite.
