Bug#1048443: Accepted igv 2.18.5+dfsg-2 (source) into unstable

[Santiago Vila]

For the record: I've also reenabled CI for this package again in the web 
interface.

(I've had to disable non-working jobs, but I think it's better to have
a green pipeline and try not to regress from that than not having a
pipeline at all).

Thanks.
