Remove libres PlotConfig dependency

- Updating tests to work without enkf plot_config
- res plotConfig made default
- libres version bumped to 2.6.a2

Clone tag only

There were merge conflict issues appearing with cloning first and then
checking out (although it shouldn't). Cloning tag only might solve it.
And anyways that should really be the preferred way, it's faster and
downloads only the part we're interested in.
