Ensure consolidation/annotated-command has the right version

[drupol]

During the development of Atomium, we noticed that some builds were failing on Drone while using composer install --prefer-lowest using Drush 8.2.0.

See: https://drone.fpfis.eu/ec-europa/atomium/496/22

It seems that when downgrading consolidation/robo from 1.4.6 to 1.3.0, the dependency consolidation/annotated-command gets downgraded from 2.12.0 to 2.9.1.

Unfortunately, the version 2.9.1 doesn't contain the class Consolidation\AnnotatedCommand\Parser\CommandInfo::getInjectedClasses() required by Drush by 8.2.0 during Drupal install (See diff from 8.1.18 to 8.2.0)

There are 2 ways to fix this.

Either we increase the consolidation/robo version from ^1.3.0 to a higher version (^1.4.0 probably)
Either we add a dependency to consolidation/annotated-command and set the proper version.

I prefer by far the first proposition.
