Paste of CE with FAL references on wrong location leads to data doubling

[opi99]

System: TYPO3 10.4.10
contend_defender: 3.1.0
b13/bolt: 2.0.2
b13/container: 1.2.0

What I do: I copy a content element with FAL References from one page into another page into a position, where it doesn't belong, but not first position on page.

What happens:

• The element does not appear on his new position (correct)
• An error flash message pops up (correct, but I got 2 for one element, hard to read for an editor)
• The original record gets all FAL references twice (Wrong)

Why does this happen (IMHO):

• The insert of the new record is not stopped inside the DataHandler::processCmdmap_beforeStart it gets stopped inside the DataHandler::processDatamap_beforeStart so the copy of the references gets preprocessed but not postprocessed which leads to doubling the references on the source record.
• The CmdmapDataHandlerHook doesn't support negative target ids (beside the DatamapDataHandlerHook does this) for inserting Data after a given record on target page. (Maybe this leads to Copy&Paste of container element with children  #74 )
• The newly introduced $backendLayoutConfiguration->getConfigurationByColPos gets the id of the source record and thinks it needs to handle this which leads to issues in b13/containers handling

What else may be wrong:

• The BackendLayoutConfiguration::getConfigurationByColPos have a static cache on $columnConfiguration which holds configurations depending on $colPos but the result may also depend on $recordUid as this is a parameter for the hook manipulateConfiguration (Maybe the $recordId was meant as a hint/helper but b13/conteiner returns different results).
