and request them each session. Pass these tokens to the project import data.
This prevents the need to encrypt these tokens and clear them in case they
expire or get revoked.
For example, if you deleted and re-created OAuth2 keys for Bitbucket, you would get
an Error 500 with no way to recover:
```

```
Closes#1871
Importing a JSON file with only one Subversion project lead to confusion
over whether the system was working. Provide status why these projects
could not be imported directly.
Closes#1531
Fix missing GitHub organisation repositories on import page.
Private repositories belonging to organizations rather than users can't be imported because `client.repos(org.login)` was requesting `/users/:org_login/repos` (which only returns public org repo's), while we need `/orgs/:org_login/repos` (which includes both public and private). The `client.org_repos` method does this.
cc @marin This is a bug in 7.8.x, but I'm not sure if it needs a minor release now or if it can go in 7.9.
