[SYSTEMDS-2788] Fix list-append validation, write error handling

This patch fixes an issue of invalid list-append validation. For lists
appends, we can append objects of any size and thus ignore inferred
dimensions (from cbind/rbind). However, if the dimensions of the
appended matrix where known, the existing validation code incorrectly
raised errors (for unknown dimensions only warnings, that's why it did
not show up in other scripts).

Furthermore, this also improves the error handling if due to
script-level mistakes we compile a spark write instruction for lists.
