Fix URL encoding error loop

Description:

If an error is detected call stop loading explicitly to avoid getting into weird URL loading loops.

Steps to test this PR:

1. In the above task click on the link with the name "bad privacy triage link" - it won't load but will show an asana popover. Click on the link in the popover to open that in a new tab.
2. The URL will fail to load and show the error screen.

Testing checklist:

• Test with Release configuration
• Test proper deallocation of tabs
• Make sure committed submodule changes are desired

Unfortunately the fix doesn‘t work for me: the page continues endless loading loop blinking with the Progress Bar
There's also a DDOS side effect: the brows
er hangs if I try to select the Address Bar while it tries to process the test request or when I open a New Tab (see screenshots)

BTW, this loading problem is fixed in #516

Will close this one since you fixed it already. :)
