DO NOT MERGE Fix the set of activities when configuring a preferred activity.

Previously the set of activities for the intent filter identifying the
activity was used, however as this one activity may be configured as
preferred for multiple intent filters, this set might not correspond
to the other intent filters. This change fixes the issue by obtaining
the set of activities independently for each intent filter.
