Selecting Dashboard causes exception, when no data

[matleppa]

In Next, when Dashboard is selected in main menu, an exception occurs, if no data is found.

The problem seems to be following:

1. connect API to a Proxy with Proxy base path XXX
2. generate calls using XXX
3. wait cron to update traffic data from ES to local DB
4. change Proxy base path to YYYY
5. generate calls using YYYY
6. wait cron to update traffic data from ES to local DB
7. Select Dashboard period Last 7 days (or Last 24 days)

Current results

7. Statistics for the YYYY are displayed. In addition to that also following is seen: "Exception from Tracker recompute function:
   meteor.js?hash=6d285d84547b3dad9717a7c89c664b61b45ea3d8:942 TypeError: Cannot read property 'localeCompare' of undefined..."

Expected results

7. At least no exception. But which data? Should also traffic with previous Proxy base paths to be shown?
