This fixes the Gify posts from our channel bot
I added this check when I found a bug about no image preview in message.
Too bad I didn't add testcase for it...
Better to comment line that removing them so we can revert it/improve patch when we will have the bug again.
you can add autotest about it in
> create a json file + ref
add it in "void MessageTest::shouldParseJsonMessage_data()"
So we will be sure that we will not break it in the future.
