Replication of InnoDB into ColumnStore ends in SEGV in plugin

This is an MCOL equivalent of DBAAS-4585. The evidence so far is that when columnstore is deployed as a slave to innodb, an attempt to do INSERT INTO InnoDBTable1 SELECT FROM InnoDBTable2 ends up in SEGV in the plugin.

toddstoffel has a reproduction in dockers. t is at present unknown if it also manifests itself in plain on prem setting (let's start with verifying that).
