Subject: QFileSystemModel: fix updating QFileInfo for a node after a file
 rename

Use the correct parent path for the renamed file when creating
QFileInfo. It must be a path to the parent directory, not to the
root directory of the model.

Modify tst_QFileSystemModel::setData() to test renames in subdirs
of the root directory of the model.
