LU-3096 tests: combine dependent sanity tests

Some tests can not run as expected when previous dependent test is not
ran.
This patch combines the following sanity tests:
    test 4 is removed as duplicate of test 1
    tests 6a, 6b to test 6a
    tests 6c, 6d to test 6c
    tests 6e, 6f to test 6e
Test 0 is renamed to test 0a to allow running it separately.
