[test][freeflow] Fix header of error csv file.
Previously it was assumed that pressure is index 0 in primary variables, u is index 1 and v is index 2. This is not correct, as pressure is dim index in primary variables, u is index 0 and v is index 1. Now we use the Indices funcionality also to set the error names.
