Sort values RepoName according to ActiveRepos list.

>>> let repos = [RepoName "a", RepoName "b", RepoName "c"]
>>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge]) id repos
Right [(RepoName {unRepoName = "a"},CombineStrategyMerge),(RepoName {unRepoName = "b"},CombineStrategyMerge),(RepoName {unRepoName = "c"},CombineStrategyMerge)]

>>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge, ActiveRepo (RepoName "d") CombineStrategyOverride]) id repos
Left "no repository provided d"

Note: currently if ActiveRepoRest is provided more than once, rest-repositories will be multiple times in the output.
