MDL-49499 wrong merge: bump version to avoid "old code" problems

Because of a wrong merge, main $version (in version.php) was
reverted from 20150407 back to 20150402, leading to messages
about running older code than version in DB. By bumping main
$versionto 20150408 all problems should be left behind.
