bugfix: minor tweaks and adjustments to test

[pollend]

the test area that is configured is getting clobbered when another area is declared. I make sure to properly clear the area with air blocks so the test function correctly when its evaluated again.

I was about to be excited that you figured out how to fix the tests that started failing after the gestalt-module v7 migration!

Then I looked at the test results: https://jenkins.terasology.io/teraorg/job/Terasology/job/Modules/job/P/job/Pathfinding/job/PR-66/test_results_analyzer/

This doesn't seem to be making more tests pass. If anything, there are more failures afterwards than there were before. ❓

that's the funny thing so this change will properly clear all the blocks so its starts from empty world and re-adds those blocks for the next test. not sure why there are a few more failures. I could of selectively done this and got most of the test to pass but that doesn't seem right. Something is looking strange to me :?.
