Subject: [PATCH] Fix loadStarted signal after an in-page navigation

In-page navigations does not trigger loadFinished thus
m_lastLoadProgress is not reset to -1. Do not ignore loadStarted signal
if m_lastLoadProgress is set to 100 because it can mean a new navigation
after an in-page one.

Task-number: QTBUG-66869
