Issue when filtering list results in zero elements

[getflourish]

I’m using this component with a list that can be filtered. It is possible that the filtered list returns an array of zero items which results in:

[Vue warn]: Error when rendering component <vue-virtual-scroll-list>
TypeError: undefined is not an object (evaluating 'slots.length')

I guess, we can’t assume that slots are always available as you try here:

Thank your report, already fixed it on v1.0.7
