Database: Cloud database 12c.
utPLSQL: v3.0.4

Starting with a new schema.

1. Create one or more objects (func, proc or package)
2. exec ut.run(ut_coveralls_reporter());
3. A coverage report is generated.
4. Drop all non-test objects.
5. exec ut.run(ut_coveralls_reporter());

The report from step 3 is returned even though the covered objects have all been dropped.

Side note: I don't think it's related but, I do have one test package that tests a function in a different schema. It's not related to the objects above and doesn't seem to affect the report.
