[Bug] regression since PR #356 -- revert only works once

[emmanueltouzery]

Description

Since PR #356 was merged, reverting modified files for git works only for the first file. After that the action is without effect.

Expected behavior

Enter the diffview for a project in which multiple files were modified. Press X to revert the changes in multiple individual files. X should cause the changes for each individual files to be reverted.

Actual behavior

X works only for the first file.

Steps to reproduce

1. Enter the diffview for a project in which multiple files were modified (:DiffviewOpen)
2. Press X to revert the changes in multiple individual files.
3. Notice that X works only the first time
