[WIP] tests: add test for case insensitive Content-Disposition

[David Bremner]

These broken now, but will be fixed in the next commit
---

The first test is OK, but the second one currently fails. It isn't
clear to me if content dispositions permit RFC2047 style
encoding. GMime does not decode them automatically (hence this test is
failing).  What is true is that the RFC states "Unrecognized
disposition types should be treated as `attachment'". So maybe the
logic in patch 1 should be reversed to check != 'inline'.
