Card creation doesn't respect newlines

[shalgrim]

When creating a card on the web, sometimes I'll put in newlines. Those just get converted to spaces when reviewing the cards tho

that PR didn't fix it

Fixing this issue would come behind issue 12 because we need to test locally before pushing

Actually it is fixed in the quiz, so first step here will be testing if that what was what attempted to be fixed in #11. If so maybe we can just extend to viewing and editing the cards
