Handle null value in bitbucket API response for repository

[jduval87]

As pointed out in issue #3143 it looks like bitbucket cloud API has started to emit null jsvalue which break the circe custom decoder for RepositoryResponse.

The proposed solution is a bit naive. And I hacked a test around with what is already available.

Feel free to edit.

Scala Steward has failed ever since on Bitbucket Cloud. Could someone merge this PR? <3
