🐛 Use default collection img if one is set

[ShanaLMoore]

Summary

When a user sets a default image in Settings, it should override the true default image (that comes from Hyrax). Previously, the collection image did not change even after the user set one. The logic needed to be swapped.

Issue:

• Default Collection image missing notch8/palni_palci_knapsack#76

Expected Behavior

When no default image is set, it'll use the application's default image. (this was tested using Pals knapsack, who've customized their default image to be the blocks instead of a blank file)

When a default image is set in the settings, it should override the application's default image
