jSparc analysis sessions Coincidences

[153957]

Creating a jSparc analysis session is currently buggy.
Possibly due to changes to sapphire.analysis.coincidences.Coincidences.
It created coincidences with less than 3 events, which should not occur.

Check where the bug occurs, perhaps changes in SAPPHiRE? (version 0.10.1 is currently used on publicdb)

See #38.

I deleted all Coincidences (publicdb.coincidences.Coincidences) which had no Events.
We will see if this occurs again.. I suppose that the coincidences without events may have been caused by cleanups, since we no longer needed those events because their coincidences had been processed the events could be removed from the database. However, we did see such 0-fold coincidences for recent analysis sessions.
