LibJS: Use array-like size for IndexedProperties::is_empty()

Browse source 
Some things, like (the non-generic version of) Array.prototype.pop(),
check is_empty() to determine whether an action, like removing elements,
can be performed. We need to know the array-like size for that, not the
size of the underlying storage, which can be different - and is not
something IndexedProperties should expose so I removed its size().

Fixes #3948.
