Use 'SubGRB' to identify subthreshold GRBs
Previously was using a parameter 'NoticeType' to idenfity sub-threshold GRBs. However checking a sub-threshold GRB VOEvent this field does not exist: https://sentry.io/organizations/ligo-caltech/issues/998630013/events/da05309eed5645e9aafd582186965478/#extra
Since we are switching to have a separate search for sub-threshold GRBs (search=='SubGRB') we can instead use this.
I changed test_raven_without_initial_circular to have a sub-threshold GRB so that we can see that this change works.
