Remove broken Travis-CI builds (#2661)

* Remove broken Travis-CI builds

Remove the optional condaforge-rc, netcdf4-dev and pynio-dev builds. These
have been continuously failing (due to broken installs), so we shouldn't waste
time/energy running them.

* Install latest miniconda

* Make appveyor default to python 3 miniconda
