Adding 100 different test cases for the ReorderAlgorithm.
The test cases are randomly generated using generateRandomTestCase()
the boards are generated once and then written in the file
reorder_algorithm_test_cases. I will leave the code to generate
the boards in the Test even though is not used anymore in case
we need to generate more boards later on.
Also, I found that the ReorderAlgorithm was not deterministic,
meaning that it could generate two different results with the same
inputs (views positions and view being drag positions), because
it was traversing a map whose has was the object id which is
random. So I sort the views before traversing them.

It also adds an assets folder inside of Launcher3 tests.
It also fixes a bug in fullReorder.
