This two-line change fixes a crash in the front end that occurred
under the following circumstances:
* A server had more than one announcement,
* A user was displaying the announcements, and
* An announcement was deleted (or unpublished, which amounts to
the same thing.)
As might be expected, the bug was caused by attempting to access a
notification using an index value outside the bounds of the existing
announcements. Specifically, in two places. First,
`_markAnnouncementAsRead` attempts to modify announcements based on
the current index. This is what caused the front end crash. Second,
when rendering the `Announcements` component, the code paginates the
announcements and displays the current one. This did not cause a
crash, but caused the front end to confusingly display a blank
announcement (in situations that would have caused a crash) with no
way for the user to navigate back to previous announcements.
This commit fixes both issues by adding a check to ensure that the
code never attempts to access an announcement with an index greater
than or equal to the number of announcements present.
