Fix YAML multiline config for package names (#358)

* Use '>-' instead of '>' for YAML multline when creating package names.

**Currently I can't reproduce the error that is shown in the issue.
Since it's a simple fix I provided a PR anyway but we need to test this
more before we merge it.**

The extra newline at the end of the string can cause JSON parsing errors
as reported by @cbeaujoin-stellar .

This change will strip the newline character after the name

fixes #357
