Clean up leftovers of src:network-manager 1.6.2-3+deb9u2+0.tails1 in our custom APT repository
Originally created by @CyrilBrulebois on #17676 (Redmine)
Seen while preparing the 4.6 release:
ssh reprepro@incoming.deb.tails.boum.org tails-merge-suite "$RELEASE_BRANCH" "$TAG"
Will not copy as not found: gir1.2-networkmanager-1.0.
Exporting indices...
tails-diff-suites
seems to indicate a match between both suites, so we
should be good; but it would be nice to consider the extra clean-up to
avoid such noise next time.
