We should fix the build first

@lchrusciel build errors are fixed now 😉

The base of this pull-request was changed, you need fetch and reset your local branch
if you want to add new commits to this pull request. Reset before you pull, else commits
may become messed-up.

Unless you added new commits (to this branch) locally that you did not push yet,
execute git fetch origin && git reset "more-than-2-dots" to update your local branch.

Feel free to ask for assistance when you get stuck 👍

I've moved your fix to 1.9, to have it available earlier, but can you add one more spec case here: https://github.com/Sylius/SyliusResourceBundle/blob/1.9/src/Component/spec/Metadata/MetadataSpec.php, to avoid regression in future?

Thank you, Francis! 🎉

@lchrusciel sure I will open an other PR based on 1.9 this time 😉
