Autorun_multiqc_stats_collect complains prematurely

[TCLamnidis]

The new check added in 1.2.0 for checking for result consistency happens before the check for existing multiqc_data files. As such, when any individuals do not have output yet, the script will throw out warnings about file corruption or results being outdated.
This is clearly not intended, and needs fixing in a patch 😬

Here's an example of the errors:

## collect_results.py: 1.2.0
