initialized one of the three vectors.

@romainbrenguier I am not entirely sure the modified initialisation code actually initialises the intended members.

This seems ok, but maybe a clearer solution would be to declare the string_constrainst explicitely:

string_constraintst constraints;
constraints.existential = equal_exprt(char_sym, str[f.arguments()[1]]);
return {char_sym, constraints};

to replace the last two lines.
