When quantity is more than the max - it shows wrong 'slots left' message

[Valentina R]

To reproduce create a product with quantity 10 (max 10), then book a slot for 5 people.

Then try to put 10 in the qty field - it works ok → shows ‘There are a maximum of 5 places remaining on ...’

Then try to put 11 in the qty field - it doesn't work ok → shows ‘There are a maximum of 10 places remaining on ...’
