[TEST] add more test on otb segmentation apps

Browse Source 
Even though not all errors are caught by these new tests, it could
expose if otb is broken or if processing api is changed to adopt
optional status of parameters at run-time.

`alg.processAlgorithm()` is running and failing correctly.
But `parameter.checkValueIsAcceptable()` and `alg.checkParameterValues()`
aren't working as expected.
