social_activity does not need to depend on social_font

Problem/Motivation

The social_font module provides a UI for site administrators to change the default font used on the site.

The social_activity module displays an activity stream and provides the notification centre for the OpenSocial site.

The two modules are unrelated and work at different parts of the page request. However, social_activity depends on social_font because Drupal's configuration management system incorrectly detects that the field.storage.activity.field_activity_entity configuration depends on social_font.

A site implementing a custom theme, or a subtheme of the socialbase or socialblue themes may want to uninstall social_font because it injects CSS into the page in a manner that makes it difficult to override; but keep social_activity because it provides important functionality. Trying to remove social_font right now takes social_activity with it, which is undesirable:

$ drush pmu social_font
The following extensions will be uninstalled: social_font, social_activity
Do you really want to continue? (y/n): n
$

Proposed resolution

Remove the dependency on social_font from social_activity and its field.storage.activity.field_activity_entity configuration.
