Commands updated to allow parent bundle

Hi,

We use that because our target bundle are parent with other and we need to migrate it.

Example:
  1 - Bundle A extends Bundle B
  2 - Migrations are in bundle B
  3 - But command "claroline:migration:upgrade 'Bundle B' --target=farthest" execute Bundle A migration

With this pull request, if we use this command "claroline:migration:upgrade 'Bundle B' --target=farthest" migrations of Bundle A will be executed.
