Creates many empty diffs

[tobyS]

One of the recent changes introduced that refactorings might contain many empty diffs in addition to the relevant ones, see http://files.schlitt.info/tmp/diff_issues.patch.

To reproduce this diff do the following:

1. Checkout https://github.com/Qafoo/changetrack revision 60a94df5c2d761f6af6ceb3ae9e0dd979f17a40a
2. Move src/main/Qafoo/ChangeTrack/Analyzer/Vcs/GitCheckout.php -> src/main/Qafoo/ChangeTrack/Analyzer/Checkout/GitCheckout.php
3. Execute refactor fix-class-names src/ test/ > diff_issues.patch

Btw. the intended changes do not occur in the diff at all.

@tomphp: I guess you are the right one to ping for a potential fix?

@tobyS I thinkt this should be pretty straight forward to fix, I'll take a look at it tomorrow.

This has been fixed in the PatchBuilder library, simply run composer update and the empty diffs should go away.
