This one is directly related to ----BSERV-3751 and also to https://jira.atlassian.com/browse/BSERV-10293

Previously the feature "Allow historical aliasing of projects and repositories" has been integrated, which from my perspective is breaking Bitbucket for previous users that rely on the fact that the old URL are not valid anymore, which was and is the expected behaviour. This change changes this default behaviour and in our case causing troubles. From my point of view this has to be configurable either globally or on renaming a repository by providing a checkbox "Alias to old repo?". In both cases the default doesn't matter as long it is a choice, but I'd vote to default to the old behaviour.
