Temporarily degenerateFunctor always return false in test Ransac::execute.

Test failed. Probably something wrong with Ransac.
Changed TrueDegenerativeFunctor to FalseDegenerateFunctor

Why in the world I wanted to have it...
Made Ransac produce more stable results
Added new test of Ranasc::Execute method

1) test with almost uncontaminated data - no fails occurs (not real
data)
2) test with contaminated data - no fails occurs (needed to improve)
