for more information on this change.

IGKJ4*02 has more mutations but aligns on the whole length of the sequence.

Sequences are identical (on the region where the read is). Therefore we have
to offer alternatives.

It is not clear why the bugs are new.

May fail on older servers. This is a pity that get-sequences fail because of
that.  We output a message so the user doesn't abort the script because s⋅he
doesn't see anything happening.

Useful so that make doesn't tell it has failed while it was just the file that
already existed
