fix: swapped output of symlink (#3361)

## Changes
Bug fix: before, on installing pipelines for the first time, users are
told that pipelines is reinstalled, while when overwriting their
pipelines symlink, users are told pipelines is installed, without
mention of the deletion.

Swapped output of print statements to match the actual expected output.
