Expanding participant count throws TypeError

Increasing the participant count calls updateField('participantsCount', …), which recreates the array by spreading prev.participants[index] into each new slot. For indexes that did not exist previously this value is undefined, and object spread on undefined raises Cannot convert undefined or null to object. The first attempt to add a second participant will therefore crash the form and prevent multi-person bookings.
