Add HTTPS URL check to accountSettingsURL / editProfileURL

[6a-62]

Summary

Workaround for instances that registers their URL as "https://instance.url", as this breaks the Account Settings & Edit Profile webviews in Metatext.

Fixed this by adding check for an existing HTTPS prefix in accountSettingsURL or editProfileURL.
