Bug when key exists in others

[syrte]

adstex/adstex.py

Lines 394 to 398 in 5723da4

	if (key_exists and args.update) or (
	key_exists_in_others and args.merge_other and args.update
	):
	bibcode = extract_bibcode(bib.entries_dict[key])
	bibcode_new = entry2bibcode(bib.entries_dict[key])

When key_exists_in_others is True and key_exists is False, the procedure will crash at bibcode = extract_bibcode(bib.entries_dict[key]), because bib.entries_dict does not have key there.
