Update the test_davinci_tupling_array_taggers qmtest adding a few lines showing how to store the mctruth information related to the extra particles in the event, beside the ones in the decay chain.
In order to retrieve correctly the mctruth information, the input file has changed and the reference has been updated accordingly.

For example:
