[NT-912] Experimental read more button loading bugfix

[justinswart]

📲 What

Addresses a bug in which the read more button in our native_project_page_campaign_details experiment would sometimes not show the loading indicator correctly.

🤔 Why

This button is meant to display a loading indicator until the Project has been refreshed and hydrated with its rewards.

🛠 How

Removed some problematic skipRepeats() that were preventing the button from being put back into a loading state after the cell was reused by the table view.

✅ Acceptance criteria

Using link conditioner, charles, airplane mode, or your favourite method of breaking your internet connectivity, put yourself in variants 1 or 2 of the native_project_page_campaign_details experiment. Navigate to a project.

• In variant 2 observe that if the project refresh errors, the read more button remains spinning and disables to taps.
• In variant 1 observe that the button is tappable without a loading indicator.
• In all scenarios of variant 2, the read more button should not cause the view to freeze or be tappable until rewards have been refreshed.
