Bugfix for Hover which is visible above other application windows. ec…

…lipse-platform#2534

This patch is fixing the problem, where the HoverManagers listeners are
deregistered but the hover is still visibile on top. This happens when
the hover was sticky eclipse was minimized and put back on foreground
after it. THe shell visibility was set to false explicitly.

Originally the isVisible() was returning false and it won't be set to
visible explicitly.
