[TASK] Add check to TV extension config

[derhansen]

Best configuration for Content migration

• enable.oldPageModule = TRUE
• enable.selectDataStructure = FALSE
• TV min version 1.8.0

With this configuration, the site admin can see both the TV and Fluid Backend layouts (only on root page with storagePid set)

Todo

• Re-arranging existing or creating new content elements in a Fluid Template Page is not recommende, when TemplaVoila is still installed. Content will be moved to default column!
• Check this on other TYPO3 Installations
• Root cause: correctSortingAndColposFieldsForPage - called by hook in TYPO3 core
• If converting FCEs to Grid Elements, then both TV and GridElements must be installed. (GridElements conflicts with TV)
• Grid Elements will not show "Insert Record" references when TemplaVoila is installed. No, Shortcut Records were created wrong
