build-ts: keep a package homepage that points outside the repository (0.86.9) (#34)

* build-ts: keep a package homepage that points outside the repository

orderPackageJson derived homepage from repository.url on every build, so a
package could not link its npm page to its API reference: the build put the
repository readme back and the clean-tree check failed. A homepage inside the
repository, or none, is still derived as before.

* Release dev, dev-test and dev-ts together as 0.86.9
