rebase: properly handle chains of markers with missing nodes

As obsolescence markers can contains unknown nodes and 'allsuccessors' returns
them, we have to protect again that when looking for successors of the rebase
set in the destination.

Test have been expanded to catch that.

import os

if os.environ.get('COVERAGE_PROCESS_START'):
    try:
        import coverage
        import random

        # uuid is better, but not available in Python 2.4.
        covpath = os.path.join(os.environ['COVERAGE_DIR'],
                               'cov.%s' % random.randrange(0, 1000000000000))
        cov = coverage.coverage(data_file=covpath, auto_data=True)
        cov._warn_no_data = False
        cov._warn_unimported_source = False
        cov.start()
