Typo in directory.
Operations cancelled if any dependencies fail with errors.

Example of log where both operations succeed:

```
Starting Synchronise
Executing CDOCommitImportOperation
Github API call: https://api.github.com/repos/3squared/sqkdatakit/commits
Executing CDOUserImportOperation
Github API call: https://api.github.com/users/blork
Github API call: https://api.github.com/users/lukestringer90
Finished Synchronise
```

And when the `CDOCommitImportOperation` errors:

```
Starting Synchronise
Executing CDOCommitImportOperation
Github API call: https://api.github.com/repos/3squared/sqkdatakit/commits
Executing CDOUserImportOperation
Dependency 'CDOCommitImportOperation' errored; Error Domain=NSCocoaErrorDomain Code=100 "The operation couldn’t be completed. (Cocoa error 100.)"
Dependency 'CDOCommitImportOperation' cancelled
Github API call: https://api.github.com/users/blork
Github API call: https://api.github.com/users/lukestringer90
Finished Synchronise
```

As `CDOUserImportOperation` is dependent on `CDOCommitImportOperation`
succeeding it is not executed (cancelled upon entering the queue).
