Issue with QC tests neither in stage passed nor failed (no 'results' entry in mongo DB test object)

We experienced a strange issue with local DB v2.3.5: For some modules we couldn't create e-summaries. We just received an error message with a python traceback on the local DB webpage instead of the usual list of analyses to choose from. (See this mattermost thread: https://mattermost.web.cern.ch/itkpixel/pl/bjno66dom7yk3yz64z41iewjmr). It turned out that this issue was due to probably inconsistently processed QC tests. In the list of "Candidate test runs of this stage" there would be just a 'N/A' instead of 'Passed' or 'Failed' in the 'QC passed' column. Manually deleting these tests marked 'N/A' in the Mongo DB using mongosh solved the issue.

Therefore, it would be very useful to have an option to delete this kind of test results using a button directly in the web interface.
