The last portage version is used instead of latest

[ferki]

If the last portage version listed in Manifest file is not the latest, then it's still selected to be used.

For example today's portage Manifest says:

In this case, 3.0.9 is used with this action (which is the last), instead of 3.0.14 (which is the latest).

If we could sort the file content before the last line is selected, then it would solve this problem. I'll try to send a PR about it shortly.
