gio/tests/converter-stream: add a new test, rename an old one
Add a test that the decompressor input streams handle truncated data correctly. (They do; I wrote the test thinking there was a bug there, but there isn't.) Also, rename the "corruption" tests to "roundtrip", since "corruption" makes it sound like we're testing how the converters deal with corrupted data, as opposed to merely testing that they don't corrupt data themselves. And fix the bug reference.
