Dashboard player indicates stream with no profiles configured still has transcoded renditions

**Describe the bug (required)** A clear and concise description of what the bug
is.

Related to #1146

When a stream is created in the API without any profiles by setting `profiles: []`, the dashboard player still indicates that there are transcoded renditions.

The result of GET /stream:

```
{
...
"profiles": [],
"createdAt": 1657228755876,
...
}
```

Here is a screenshot when the stream is active:

Notice that there are renditions that the player supports switching to.

**Expected behavior (required)** A clear and concise description of what you
expected to happen.

The dashboard player to display zero renditions when there are zero profiles configured for the stream.

**To Reproduce (required)** Steps to reproduce the behavior:

Create a stream with zero profiles (`profiles: []`) and watch the dashboard player when the stream is active.

Reproduce the issue in the dashboard player with an active stream created using profiles: []; the issue includes the relevant GET /stream response and screenshot. Inspect the dashboard player entry point that determines available renditions, and verify that the completed behavior displays zero renditions when the stream has no configured profiles.
