Postprocessing of esys fails

[nesnoj]

(HEAD: 5604829, oemof-solph version 0.5.2.dev1)

When running snakemake -j1 postprocessed_esys_appdata optimization is successful but postprocessing fails at this point:

apipe/apipe/esys/scripts/optimize.py

Line 323 in 676a411

es.results = processing.results(m)

since timeindex differs here:

               '2019-01-01 02:00:00'],
