MatchAnalysis crashes and then hangs when t5memory crashes

When t5memory crashes during a matchAnalysis (in the concrete Case "E1370 
Empty response from OpenTM2 - http://t5memory-hio.web.inetsolutions.cloud:4041/t5memory"), the MatchAnalysis worker crashes and the whole Operation finishes without changing the task-state (which remains in "matchanalysis") and giving any feedback to the user.

The error should be catched instead, a proper Event should be generated "Match Analysis failed because ...", the task should go back to "open" but with an error-icon, that tells "last Analaysis failed" and stays until a new analysis was successfully made.
