Otherwise, heavy traffic of DIS prevents routers from sending DIOs. This issue is found only in rpl-lite.

Fixes #910

@simonduq Any objections to merging this? I'm not familiar with the RPL lite code, but this PR appears to fix a real problem, cites RFC 6206 for backing, includes new tests, and the new changes seem to make sense. Overall very well done.
