The update task:

register(DeltaBuilder.update("1.0.2", "Update latestComments paragraph")
                .addTask(new BootstrapSingleResource("Paragraph update", "Updates the latestComments paragraph.", "/mgnl-bootstrap/commenting/config.modules.forum.paragraphs.latestComments.xml", ImportUUIDBehavior.IMPORT_UUID_COLLISION_REPLACE_EXISTING))
            );

Does not work when updating directly from 1.0, because the bootstrap file:
/mgnl-bootstrap/commenting/config.modules.forum.paragraphs.latestComments.xml
doesn't exist anymore on the module. The file still exists in the 1.1 module version.
In 1.1.2 it was 'changed' (noe stk and not freemarker paragraph) to config.modules.commenting.paragraphs.latestComments.xml.

Workaround:Update first to 1.1 and then to 1.1.2.
