REVISION SUMMARY
  This regression (compared to kdelibs4's direct KFileDialog usage) came
  from the fact that QFileDialog's lastVisited() only gets updated if
  the helper emits directoryEntered.
  
  So QFileDialog was setting the current dir as startDir every single
  time, overriding's KFileWidget's own logic for reusing the last dir
  initially.

TEST PLAN
  QFileDialog::getOpenFileName(this, i18n("Select file"));
  twice in a row, from the same process.

REPOSITORY
  R135 Integration for Qt applications in Plasma

BRANCH
  Plasma/5.13
