"Repeat the Roll" button not working

[dmoisset]

When I click the repeat the roll button on a chat card, I get a red notification saying: Dice roll evaluation failed: Cannot read property 'formula' of undefined.

To reproduce in FoundryVTT 0.8.8

• Create a new world using Dnd5e system 1.4.1
• Enable Better Rolls 1.6.4, libWrapper 1.8.0.0
• Create a new scene (you can use all the defaults)
• Drag a compendium character into scene (I used "Akra (dragonborn cleric)")
• Roll an insight check (rolls and pops a card in the chat)
• Click on the repeat the roll button on the card

The above has some example values, but I've seen this with every roll for every character that I tried.

Traceback in the console is:

fields.js:82 Uncaught (in promise) TypeError: Cannot read property 'formula' of undefined
    at Function.constructMultiRoll (fields.js:82)

Should be working now, give it a shot.
