Fix packaging of the tests directory (#1215)

Do not install tests as a package, but instead include it only in the
source tarball via MANIFEST.in.

I have verified that the resulting tarball installs only the 'atlassian'
package into site-packages and that the included files are sufficient to
successfully run the tests.

Fixes #1206
