Describe the bug
If the investment tables contains an row with a heatpipeline type with nonconvex=0, this does not work with the current oemof-solph version, as in the meanwhile, an error is raised in oemof-solph, if there are fixed_investment costs and nonconvex is set to false. (Before the fixed cost were ignored.)
