TT#137901 Do not clean orange background .accordion-group on hiding tooltip.

Otherwise the attribute 'open' has been removed from class '.accordion-group'
when user removes mouse from element 'search/from/to' (the 'hide' event is triggered).
Ngcp-panel should remove orange background on manual click to close accordion,
this is why we are validating 'e.target' to ignore tooltip events.
