Summary

During updating security tokens on dashboard there is an error "Unknown RPC service: update_security_token" which prevents from updating tokens. Moreover in case when first gadget on dashboard is not placed inside iframe the update phase isn't invoked at all. 

Steps to Reproduce

1. Prepare a dashboard with plenty gadgets (some with auto-refresh)
2. Make sure first gadget is not embedded inside an iframe 
3. Check console.log(s) - messages that update token is no needed because there are no gadgets on dashboard should appear. 
4. Move your gadgets, make sure that iframe gadget is on first slot
5. Watch your console, errors about update_security_token should appear in a while (you can invoke the refresh function faster using __st_refresh parameter eg. ?__st_refresh=4000)

Expected Results

• Jira should perform token updates for iframe gadgets in all cases - regardless of order
• Jira should should successfully update security tokens for all gadgets inside iframe 

Actual Results

• Jira doesn't perform token updates in case when first gadget is outside an iframe
• Jira throws an exception during token update when there is a mix of outside/inside iframe gadgets without auto-refresh.

Notes

Issue is already fixed and will be shipped with Jira 8.0.
