Handle invalid paths better in MSW wxDirDialog

Browse Source 
When setting a path including an invalid drive in IFileDialog-based
wxDirDialog, Windows returned ERROR_INVALID_DRIVE error. wxWidgets
treated this as an error and reverted to showing the old
ShowSHBrowseForFolder()-based dialog.

However, it is better to just ignore any errors produced when attempting
to set the default folder (as the code already did for ERROR_FILE_NOT_FOUND)
and show IFileDialog-based dialog anyway.
