[Bug]: HTML rendering of objects with links

### What happened?

When trying to render an HDMF (or PyNWB) object with a reference to another object, it can cause an infinite recursion error.

In the following code:

```python
from pynwb.testing.mock.base import mock_TimeSeries

ts1 = mock_TimeSeries()
ts2 = mock_TimeSeries()
ts3 = mock_TimeSeries(timestamps=ts2, rate=None)
```

`ts1` renders as expected, but `ts2._repr_html_()` and `ts3._repr_html_()` both cause errors:
