Import measures after matrixstore has been built

When building measure.analyse_url, import_measures uses the matrixstore
to find a list of all prescribed presentations.  Before this change, it
would miss any presentations that were new this month.  Additionally,
the end-to-end tests would sometimes fail because the matrixstore had
not yet been built.
