test-revert: add methodical revert to parent for working directory

Now that we can automatically generate states, we need to actually run
revert on them and check the result. While running such tests we are
checking multiple elements. The output of the `hg revert` command, the
resulting content of file, and the creation of backup file.

The first practical test is using the simple case `hg revert --all`, reverting
all files to working directory parent content.
