Issue Summary

If a dashboard's URL slug begins with "assets" (i.e. assets-dashboard) then the dashboard will fail to load on new page loads: 

Navigating to the dashboard from the dashboard list does work as expected. However, refreshing the page or copying/pasting the dashboard URL into a new tab does fail. 

Steps to Reproduce

1. Create a new dashboard where "assets" is first in the url slug (e.g.assets-dashboard)
2. Save the setting
3. Copy the dashboard URL
4. Open the dashboard in a new tab

This can also be reproduced without making the dashboard at all. It occurs without authentication or needing a valid site URL. e.g.: 

http://foo-test-fake-site-848484.atlassian.net/analytics/assets-dashboard/

Expected Results

The dashboard loads as expected

Actual Results

The text "Not found" is returned with HTTP status 404

Workaround

Add text in the URL slug before "assets" and the dashboard will load as expected. The only trigger seems to be when "assets" is the first word in the URL slug. 

So changing 

http://foo-test-fake-site-848484.atlassian.net/analytics/assets-dashboard/ 

to 

http://foo-test-fake-site-848484.atlassian.net/analytics/team-assets-dashboard/ 

will work around this bug
