Fix QTextBrowser autotest to use "file" scheme in URLs.

A security fix to QUrl that causes it to no longer interpret URLs
without scheme as local files broke QTextBrowser test case. Added the
necessary "file" schemes to URLs used in the test.

Also added a mention about necessity of using "file" scheme to
QTextBrowser documentation.
