In Session Mode:
Before this commit, autosubmit was only dependant of the back button,
but not of the session mode. In session mode, back button is ignored,
and auto-submit sould not happen in session as user has not the possibility
to go back in case he misclicked.
After this commit, the auto-submit only happens if back button is activated AND
if we are not in session mode. This is already checked inside
survey._can_go_back method and already given to the template.
When selecting 'other' option:
For a single or multiple choice question, if the user is selecting the
'Other' choice, Auto submit should not happen. Otherwize, the user has not the
possibility the type his custom answer.
Also, if the question has comment that does not count as answer, the user
should still be able to add a comment after having selected the answer.
The comment can be a complement of answer.
