Access hbonds results through new results member in count_by_ids() and count_by_type()

[pgbarletta]

Hi!
Quick PR since this makes User Guide tests with nbval fail due to the UserWarning being thrown.

Fixes:
count_by_ids() and count_by_type() throw a deprecation warning for accessing the hbonds attribute directly.
