[Technical-Support] LPS-48330 "layoutIds" hidden field won't contain checked pages correctly when pages tree doesn't load all selected nodes at first time

Hey Tibor,

1.
In ExportImportHelperImpl.java I created 2 methods which ensure a json array based on selectedLayoutIds.

2. 
I used helper logic to generate json instead of main.js logic.

Thanks,
