WD: script integer attribute values do not work

1. Open WD.
2. Click the "Scripting mode" tool button -> Show scripting options.
3. Create the workflow: "Read sequence" -> "Write sequence".
4. Set the input sequence: _common_data/fasta/abcd.fa.
5. Set the correct output sequence.
6. Edit a script for "Sequence count limit":

printToLog("test");
1

Expected: the result file contains only the first sequence from the input file; there is a message "test" in the script details log.
Actual: the "Sequence count limit" parameter becomes 0.
