Assistant: Fix index updating on startup in the remote control mode

HelpEngineWrapper::initialDocSetupDone() should be called only once
right after the initialization of the help models. Calling it on
every small update leads to recursion.

Task-number: QTBUG-36850
(cherry picked from qttools/d55407822eefbc05f7d8bb44c53b057332b5b399)
