MegaQC doesn't handle data when module was run multiple times

[fgvieira]

Describe the bug

I am trying to plot the FastQC module multiple times (like here) but, even though all looks good in the MultiQC report, only the last data seems to be stored MegaQC. That is, in the example above, only the FastQC (trimmed) data is stored; would it be possible to save both?

This is a follow up on issue MultiQC/MultiQC#2203, since it seems it is a problem on how MegaQC parses the json file from MultiQC.

To Reproduce

Steps to reproduce the behavior:

1. Run megaqc with command: upload on a multiqc report with multiple datasets
2. Select: one of the d
3. See error: only one dataset is shown

Expected behavior

Both datasets should be present.
