No, Rename() doesn't cleanup the contents. FStream is only stored (if you
load/initialize the TIniFile/TMemIniFile from a stream) so that
UpdateFile() can update/overwrite that stream with the new ini values.
When loading from a stream, TIniFile/TMemIniFile read all values inside its
constructor, just like when loading from a file.
