bp_get_user_has_avatar() always returns true if default avatar URL is filtered

bp_get_user_has_avatar() will always return true if the default avatar URL has been changed by filter bp_core_default_avatar_user

Also, I think there's a second filter available that, if used, will cause bp_get_user_has_avatar() to always return true.

That filter is bp_core_avatar_default

Yikes, it's not going to be very fun to track down and ensure all the filters are mirrored :) We really need unit tests for this.
