only rename wheels that go to scipy-wheels-nightly

[mattip]

missed this in gh-84: we only want to add the date to the wheels at https://anaconda.org/scipy-wheels-nightly/numpy/files, since the ones at https://anaconda.org/multibuild-wheels-staging/numpy/files are meant to be PyPI candidates. Note that since this PR is from a fork, the changes will not be tested.

for f in wheelhouse/*.whl; do rename_wheel $f; done else ANACONDA_ORG="multibuild-wheels-staging"; TOKEN=${NUMPY_STAGING_UPLOAD_TOKEN}; fi '
/home/travis/.travis/functions: eval: line 109: syntax error near unexpected token `do'

Looks like travis is spinning its wheels on the upload, may want to cancel.

Thanks Matti.
