Migrate script hit error for media without section

[ermbutler]

The migrate script appears to be having an issue handling media without a section.

When attempting to migrate I hit this error, and then was able to bypass it by moving all the project media into sections:

14 memberships will be created (1 already exist).
1 sections will be created (0 already exist).
3 versions will be created (1 already exist).
1 media types will be created (0 already exist).
3 localization types will be created (0 already exist).
2 state types will be created (0 already exist).
0 leaf types will be created (0 already exist).
