Inconsistent results from qmca when analysing multiple files

**Describe the bug**
While checking #4549 I noticed that at some recent point we have reordered the scalar.dat output. The columns are correctly labeled. Unfortunately, when files of different versions are mixedm qmca doesn't completely handle the situation and gives inconsistent results . They are nearly OK which suggests the correct data is being used for the most part.

**To Reproduce**

Analyze different versions of scalar files simultaneously. In the following notice the debug* results are reported consistently but the orig* ones are not. Quantities other than the energy are suspect, e.g. samples, although I noticed this first by the energy.

Archive of the respective files attached. Used qmca from develop.

```

**Expected behavior**

Either abort in this scenario (easiest) or give consistent results.

**System:**

Develop, runs & analysis on nitrogen2 with amdclang cpu nightly configuration.
