Fix rb_SUITE failing tests

Some tests in rb_SUITE failed every now and then depending on timing:

1. sometimes SASL printouts from cth_log_redirect were captured in
addition to expected printouts

2. sometimes test supervisor and server were not completely stopped
before next test case was started

This has been corrected.
