LU-1564 test: sanity test_200d fails

Because sub-tests in test_200 group and test_201 group are
the parts of one scenario and designed to be run sequentially
one-by-one, so each of which depends on previous.
Correspondingly, tests from 200a to 200h and from 201a to 201c
have been refactored into single test_200 test.
