Website event track module is an advanced event module that is required notably
in some sub modules: live, quizzes, exhibitors.
When unchecking Schedule & Tracks in event settings, submodules checkboxes
are hidden. It means that currently you may uncheck module_website_event_track
while still keeping sub modules (_track_live, _track_quiz, _track_exhibitor)
checked. When saving, modules are uninstalled, then installed again if one
of sub module is still checked.
In this commit we add an onchange so that unchecking track also unchecks all
its sub modules to effectively remove them all.
