Fixed crash caused from invalid URLs in the PageInfo dialog

Cleaned up WebsiteSettingsPopup::updatePageDetails in the PageInfo
dialog and fixed a crash from invalid URLs. When a malformed URL is
accessed, the PageInfo dialog will still display the URL, but won't
apply any custom coloring (this only applies to well-formed URLs).

TEST=Visit a malformed URL, such as 'data:html,foo<script', and open the
PageInfo dialog by long-pressing on the URL. The URL should be displayed
(but not colored), and Chrome should not crash.
