CLC-2562: MyFinAid notifications: Processed & received statuses need to be available at a glance

https://jira.media.berkeley.edu/jira/browse/CLC-2562

- Stop concatenating status messages to the title of myfinaid activities.
  Status messages are now shown on a separate line within the unexpanded activity block,
  just underneath the title
- Wrote test to check that this concatenation no longer occurs.
- Wrote tests to confirm the status message given for alert, message, and financial types

In the dashboard activities view:
- Added status line underneath the title for items that have a defined status field
  * this includes BearFacts as well as MyFinAid messages (check with Bernie on this!)
- Changed the "View in {{activity.emitter}}" buttons to links that read "More info"
- Placed the "More info" links on a separate line
