Keep QIDs in json output

[Adafede]

When using -j the corresponding QID does not appear in the output. This is somehow problematic as labels change, while QIDs don't.

Example:

python3 classify.py -d ./ -m 'InChI=1S/C28H32O15/c1-39-14-7-15-18(12(32)6-13(40-15)10-2-4-11(31)5-3-10)22(35)19(14)26-27(24(37)21(34)16(8-29)41-26)43-28-25(38)23(36)20(33)17(9-30)42-28/h2-7,16-17,20-21,23-31,33-38H,8-9H2,1H3/t16-,17-,20-,21-,23+,24+,25-,26+,27-,28+/m1/s1' -j

vs

python3 classify.py -d ./ -m 'InChI=1S/C28H32O15/c1-39-14-7-15-18(12(32)6-13(40-15)10-2-4-11(31)5-3-10)22(35)19(14)26-27(24(37)21(34)16(8-29)41-26)43-28-25(38)23(36)20(33)17(9-30)42-28/h2-7,16-17,20-21,23-31,33-38H,8-9H2,1H3/t16-,17-,20-,21-,23+,24+,25-,26+,27-,28+/m1/s1'

Hope this makes sense
