Failed to aptly publish drop if a trailing / remains in the prefix

[frntn]

Detailed Description

Failed to aptly publish drop if a trailing / remains in the prefix

Context

Starting from this :

aptly mirror create graylog http://packages.graylog2.org/repo/debian/ trusty 1.3
aptly mirror update graylog
aptly snapshot create graylog-20170801 from mirror graylog
aptly publish snapshot -passphrase-file=.publish -distribution=trusty graylog-20170801 :v16/mirror/packages.graylog2.org/repo/debian/

Trying to drop the published content using the extact prefix used for the previous publish snapshot (trailing /)

aptly publish drop trusty :v16/mirror/packages.graylog2.org/repo/debian/   # <-- FAIL

Successful completion occurs after removing that last character (trailing /)

aptly publish drop trusty :v16/mirror/packages.graylog2.org/repo/debian   # <-- SUCCESS
