CLC-3189 - LiveUpdates: Eliminate the "checking for new data" prompt

https://jira.media.berkeley.edu/jira/browse/CLC-3189

Eliminated the "checking for new data" prompt that used to appear when a user's dashboard was loading.

The message was considered to be "dishonest" since it didn't necessarily always get the new data because of server caching issues.
