Missing push animation for unsubscribed episodes in search result

### Expected behavior

In Podcasts tab, when you tap an episode in the list of search result, the detail screen appears with push animation.

### Actual behavior

Push animations does not happen for unsubscribed episodes but for subscribed episodes.

### Steps to reproduce the behavior

1. Launch the app and select the Podcasts tab
2. Search any episodes
3. Tap an episode which is not subscribed
4. The detail screen appears without push animation

##### Tested on [iPhone 14], iOS [16.2], Pocket Casts [7.33.0.3]

Reproduce the issue in the Podcasts tab by searching for an unsubscribed episode and opening its detail screen, then compare that navigation with a subscribed episode. The issue provides no file or test names; done means both search-result paths display the detail screen with the expected push animation on the tested iPhone and iOS versions.
