Alligned version number with version on moodle.org

[Flottertotte]

I experienced the following problem:

1. In my moodle install, I checked for available plugin updates
2. Regarding the Oauth plugin, the system tells me: "There is a new version 2016061204 available! Release 2.3 (Build: 2016061204)"
3. I let moodle install the update (which is taken from moodle.org)
4. After successful installation, I do step one again and still see for the Oauth plugin: "There is a new version 2016061204 available! Release 2.3 (Build: 2016061204)"
5. I check the version number in the version.php file and see that the version of the plugin is: 2016061202

Therefore I have changed the version to 2016061204
