Cleanup: use DiveTripModelBase::clear() to reset the log

Introduce a DiveTripModelBase::clear() function that cleanly
clears all dive data inside a beginResetModel()/endResetModel()
pair. Thus, the UI will be cleanly reset and we can remove
explicit calls to
 - graphics->setEmptyState()
 - mainTab->clearTabs()
 - mainTab->clearTabs()
 - diveList->reload()
from MainWindow::closeCurrentFile().
