Swift event ingestion: Missing localization (session transaction closed)

[Theodlz]

Looks at production, recent SWIFT event's localizations are missing. The GCN Event are being created, but the localization is missing.

1. Unfortunately (or fortunately!) errors are all caught and we have minimal insight over what could have gone wrong.
   However, looking at the logs, we understand that at some point an error has occurred, and the session wasn't rolled back. Therefore, we get that "the transaction was closed", which means a rollback is needed where the error handling has occurred (try/except), to allow to post the events that come after the one that caused an error to happen.
   Also, it seems that the error that might have caused the initial error is: Failed to consume gcn event: Invalid propotation filter value: could not convert string to float: 'undefined'.

2. Running SP locally (not Icare, just SP), we get the following error while ingesting some events:

    raise ValueError("bins must be monotonically increasing or decreasing")
ValueError: bins must be monotonically increasing or decreasing

meaning that the prob variable (passed in digitize as bins) is not motonone. Some values might repeat themselves, or aren't ordered. I am not sure that this should be an issue, but the digitize method from numpy treats it as is.
