parsers: fix two leaks in index_ancestors

Both happy paths through this function leaked the returned list:

1) If the list was of size 0 or 1, it was retained an extra time and then
   returned.

2) If the list was passed to find_deepest, it was never released before
   exiting this function.

Both paths spotted by cpychecker.

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.start()
