1599281 - Fix TypeError: this._securityUI is null at updateSecurityUIForSecurityChange

While running test devtools/client/responsive/test/browser/browser_preloaded_newtab.js with the devtools.responsive.metaViewport.enabled pref set to true, I hit this exception:

TypeError: this._securityUI is null at updateSecurityUIForSecurityChange@chrome://global/content/elements/browser-custom-element.js:1545:9

It appears that the securityUI getter has a few paths where it could return a null value. The updateSecurityUIForSecurityChange method should handle this case gracefully.

Hi,

I will move this over to a component. If this is not the correct component please feel free to change it to an appropriate one.

Thanks.
