https upgrade bug on startup

[dscrobonia]

Everytime i restart the HUD the https upgrade has a bug on the first load. I have to refresh the tab to have it work. The sharedData.upgradedDomains doesn't include the target page. This means that scope, alerts, history, and any other tool taht depends on the correct protocol for the api won't work

I believe this is because the domain is only added when ZAP sends the event via websockets. But on the first load the event is sent before the HUD can receive it (?). Probably should wrap this into a more robust startup, which I should focus on in #160 . This may require a more thorough description of how startup works.

I'm seeing this issue (frequently) too, e.g.:

ERROR errorHandler: TypeError: sharedData.upgradedDomains is undefined
     @https:    https://zap//zapCallBackUrl/-6949015154753721973?name=tools/commonAlerts.js 95:: {}

Interestingly only the right alert tools are broken, when clicked it throws:

ERROR errorHandler: [object ErrorEvent]: {"isTrusted":true} -6949015154753721973:631:3
     TypeError: sharedData.upgradedDomains is undefined

the left alert tools show the dialogue when clicked.

For me reloading the tab does not fix it, have to restart the browser.
