revdeps new errors in rbindlist due to class mis-match

@ben-schwen

revdep heuristicsmineR has the following new error when running examples if data.table from github master is installed,

* checking examples ... ERROR
Running examples in 'heuristicsmineR-Ex.R' failed
The error most likely occurred in:

> ### Name: as.petrinet
> ### Title: Converts the object to a Petrinet
> ### Aliases: as.petrinet
> 
> ### ** Examples
> 
> data(L_heur_1)
> cn <- causal_net(L_heur_1, threshold = .8)
Error in rbindlist(l, use.names, fill, idcol) : 
  Class attribute on column 7 of item 2 does not match with column 7 of item 1.
Calls: causal_net ... merge -> merge.data.table -> rbind -> rbind -> rbindlist
Execution halted

git bisect says this started happening after merging #5263
@ben-schwen can you please have a look? (you were author of that PR)

A similar error, started happening after merging the same PR, in revdep table.express:

* checking tests ...
  Running 'testthat.R'
 ERROR
Running the tests in 'tests/testthat.R' failed.
