Import bitbucket issues that are reported by an anonymous user

For these kind of issues, the "reporter" field is present but zero.
In such a case, "fetch" will not return the default value, but it will
return nil.
Hence, importing fails, because the "username" field of nil is referenced

Fixes issue #44381
