git review list fails with newer gerrit versions

The trusty git-review packages list command fails with newer versions of gerrit:

$ git review --list
Traceback (most recent call last):
  File "/usr/bin/git-review", line 1196, in <module>
    main()

    list_reviews(remote)
  File "/usr/bin/git-review", line 697, in list_reviews
    len(review_info[REVIEW_FIELDS[i]])
TypeError: object of type 'int' has no len()

The reason is a missing string conversion in the list_reviews function:

diff --git a/usr/bin/git-review b/git-review
