client_reset::transfer_group() can crash when transferring tables with dangling links

[sync-by-unito]

During client_reset::transfer_group() we can have two lists - the source list is a list of links where the primary keys are [1, 2, 3] and the destination list has primary keys [1, 3] but it also has a dangling link to {}2{}; we go through the destination, establish that the common prefix is 1 and the common suffix is 3 but there's no {}2{}. So we create the object in the destination realm with a primary key 2 which makes the dangling link not 2 anymore, and then insert 2 into the destination. now the destination list is 1, 2, 2, 3. This crashes IntraRealmObjectConverter::copy_list() which expects the size of lists to be the same after copying over all the properties. You have to get a little unlucky to have this happen in that you have to be copying a table that links to another table where the target table's TableKey is greater than the table that links to it.
