#255 Configuration error in case of workflows generated from Template

[Gabor Hermann]

False positive “Nothing in the set relating the job execution model of Binary type has been defined” error message expected if
the workflow is generated from a template where within a job the fields of "Resource" and "Grid" are opened, the "type" is PBS, and
during the subsequent job configuration "Resource" field will be changed by the user.
The confusion of naming ("Grid" in template, "Resource" in job config) must be investigated as well.
