Implement a unit test for the FindRecalSeries function

[hechth]

The user facing FindRecalSeries function has no unit test so far, only all of the sub-functions have tests. There should be another test added for this function to insure that it works reproducibly, especially given that the test for the Galaxy tool wrapper is failing.

The test should take a recalibration list and check the output whether it is consistent across runs, so just comparing the actual output vs. the expected, which would be the output at the first run.
