Mats Kindahl cbe06c3b72 Handle undefined ignore_invalidation_older_than
If `ignore_invalidation_older_than` is undefined, it is set to maximum
for `BIGINT` type. This is not handled in `continuous_aggregates`
information schema so the column shows up as a very strange value.

This commit fixes this by checking if `ignore_invalidation_older_than`
is set to maximum, and uses `NULL` in the view in that case, which will
show up as empty.
