fix: ensure contact data is refetched when changes where made

Changes in contact data caused via calls to any contact related APIs wouldn't be
reflected in the UI because it doesn't re-fetch the updated state from status-go.

This commit makes the contactsService `fetchContacts` API public so it can be
used on the profile section control to re-fetch contact data when changes to
contacts have been emitted.
