`pull`: reports wrong number of files added

[dberenbaum]

Bug Report

Description

dvc pull doesn't report the number of files actually added.

Reproduce

git clone git@github.com:iterative/dvc-bench.git
cd dvc-bench/data/mnist
dvc pull dataset/train/4

The output of the last command is:

A       dataset/
1 file added and 5843 files fetched

However, thousands of files have been added to dataset/train/4.

Expected

Something like:

A       dataset/
5842 files added and 5843 files fetched
