REVISION SUMMARY
  Dolphin shows a different text for whether it is loading the directory or currently sorting its contents.
  However, when entering a folder that causes sort criteria to change (e.g. because of different view properties in that folder), the status bar text is changed to "Sorting..." while it is still actually loading the folder.
  When loading a directory starts, reset any status bar text to ensure "Loading..." is displayed in this case.

TEST PLAN
  Configured one folder to sort by Name, the other by Date, both on slow devices.
  Went from the Name-sorted folder to the Date-sorted folder.
  Status bar showed "Loading..." instead of "Sorting..."

REPOSITORY
  R318 Dolphin
