Asynchronously deletes file.
If file is a directory, its contents are deleted recursively before file itself is deleted. The recursive
delete operation will stop on the first error.
If cancellable is not null, then the operation can be cancelled by triggering the cancellable object before the
operation finishes.
When the operation is finished, callback will be called. You can then call file_recursive_delete.end
to get the result of the operation.
