server: add tests for track_table of a materialized view (#4155)

* server: add tests for track_table of a materialized view

In the context of #91, we discovered that materialized views were
already "automagically" supported; to ensure we don't regress on this
accidental but welcome change, this patch adds simple tests.

This is basically just a copy of `track_untrack_table`, but for
materialized views.
