Messy output on `make deploy`

[robertauer]

When using make deploy (in this case for the cesapp package) the command line output is kind of messy:

...
... uploading package
["cesapp_1.1.1.deb/cesapp_1.1.1.deb"]... add package to repositories
# heads up: For migration to a new repo structure we use two repos, new (ces) and old (xenial)
# '?noRemove=1': aptly removes the file on success. This leads to an error on the second package add. Keep it this round
{"FailedFiles":[],"Report":{"Warnings":[],"Added":["cesapp_1.1.1_amd64 added"],"Removed":[]}}{"FailedFiles":[],"Report":{"Warnings":[],"Added":["cesapp_1.1.1_amd64 added"],"Removed":[]}}... publish packages
{"Architectures":["amd64"],"ButAutomaticUpgrades":"","Distribution":"xenial","Label":"","NotAutomatic":"","Origin":"","Prefix":"xenial","SkipContents":false,"SourceKind":"local","Sources":[{"Component":"main","Name":"xenial"}],"Storage":""}{"Architectures":["amd64"],"ButAutomaticUpgrades":"","Distribution":"xenial","Label":"","NotAutomatic":"","Origin":"","Prefix":"ces","SkipContents":false,"SourceKind":"local","Sources":[{"Component":"main","Name":"ces"}],"Storage":""}{"Architectures":["amd64"],"ButAutomaticUpgrades":"","Distribution":"bionic","Label":"","NotAutomatic":"","Origin":"","Prefix":"ces","SkipContents":false,"SourceKind":"local","Sources":[{"Component":"main","Name":"ces"}],"Storage":""}

The two lines starting with ... should start at a new line and not directly after the output of the line before.
A new line should be printed at the end of the output.
Maybe the json output could be formatted more neatly.
