async collection.list() not using arraycursor

[x3cion]

See https://github.com/arangodb/arangojs/blob/master/src/collection.ts#L399

I'm pretty sure the list() function should be using an array cursor. Since the underlying endpoint is deprecated, I guess this is a good reason to implement it as an AQL.

I'm sorry I can't PR this, I currently have no time to help.

This will be addressed in the next major release:
