Hello,

'guix build python2-urllib3' currently gives:

  /gnu/store/cx22ny550g97klf499yqgzx9mpvvkx1f-python2-python2-urllib3-1.26.4

Adding '--no-grafts' gives the expected file name.

Note that up until commit 2f97a666a564fea0fdcff00a0513aa8b4c2d60fe, the
store file name was actually '...-python2-python2-python2-urllib3-...'!

Not sure if this is a recent regression, or what may be causing it.

Ideas?
