Missing plotting file CMSTTBARTOT5TEV

Created by: Zaharid

See e.g. this test failure:

https://travis-ci.com/NNPDF/nnpdf/jobs/201531147

specifically:

Falsifying example: test_rebuild_commondata_without_cuts(tmp=PosixPath('/tmp/pytest-of-root/pytest-0/test_rebuild_commondata_withou0'), arg=(CommonDataSpec(datafile=PosixPath('$PREFIX/share/NNPDF/data/commondata/DATA_CMSTTBARTOT5TEV.dat'), sysfile=PosixPath('$PREFIX/share/NNPDF/data/commondata/systypes/SYSTYPE_CMSTTBARTOT5TEV_DEFAULT.dat'), plotfiles=(PosixPath('$PREFIX/share/NNPDF/data/commondata/PLOTTINGTYPE_INC.yaml'),)),

I see that there is PLOTTING_CMSTTBARTOT.yaml, but not sure if it should be the same.
