Issue: Exporting/importing a FiftyOneDataset with an annotation run results in an error

### System information

-   **OS Platform and Distribution (e.g., Linux Ubuntu 16.04)**: Windows 10
-   **FiftyOne installed from (pip or source)**: pip
-   **FiftyOne version (run `fiftyone --version`)**: 0.14.0
-   **Python version**: Python 3.8.10

### Describe the problem

Exporting a dataset with `dataset_type=fo.types.FiftyOneDataset` with at least one annotation run and trying to import it back results in an error.

I am sorry if the issue is caused by not using the interface correctly. We just started using fiftyone in our organization and I am currently working to incorporate it into our workflow.

### Code to reproduce issue
```
import fiftyone as fo
import fiftyone.zoo as foz

dirname = "C:/Users/User/test_dataset_export"

if fo.dataset_exists("quickstart"):
    fo.delete_dataset("quickstart")
dataset = foz.load_zoo_dataset("quickstart")

view = dataset.take(1)
anno_key = "test_export_import_dataset_with_annotation"
view.annotate(
    anno_key,
    label_field="ground_truth",
    url="http://localhost:8080",
    username='********',
    password='********'
    )

dataset.export(
    export_dir=dirname,
    dataset_type=fo.types.FiftyOneDataset,
    export_media=False,
    )

if fo.dataset_exists('another_dataset_name'):
    fo.delete_dataset('another_dataset_name')
new_dataset = fo.Dataset.from_dir(
    dataset_dir=dirname,
    dataset_type=fo.types.FiftyOneDataset,
    name='another_dataset_name',
    )
```
