Enable preview for gifs after enabling the gif functionality
Disable gif functionality if the preview was disabled
Addition fixes
- The gifs weren't checked if all images weren't enabled
- The subdomain wasn't checked for whitelisting if the main domain wasn't enabled
- Image clicking
- Dismiss asking for unfurling was not updating the state
Considerations
- Looked into having the "gif enabled" - "tenor unfurling" relation
embedded in the controller but it would require extensive refactoring
by implementing a data-model for unfurling whitelisted domains
Closes: #6829
