@decidim/lot-core ready to review.

@rbngzlv It'd be possible to add a system spec for this?

[josepjaume]

Yeah, current specs are too flaky (this is why this bug appeared in the first place). We should add a system test for this.

[rbngzlv]

@deivid-rodriguez @josepjaume rebased on master and added a system spec.

[josepjaume]

@rbngzlv backporting to 0.10 is necessary but I believe 0.9 is not, right?

[rbngzlv]

@josepjaume I'm not sure, the bug was detected in 0.9. Definitively we need a policy for the EOL of the previous versions.
