revert: commits 2d3e8be and b02cc11 - enable running on phpcs3 branch.

Initially, the phpcs3 branch was going to be a standalone release for phpcs version 3.x only. Now that the tests for both 3.x and 4.x work, we can merge into 1 release. So the phpcs3 branch is no longer needed.

This reverts commits 2d3e8be and b02cc11.
