Open issue in the BPO indicated a desire to make the implementation of
codecs.open() at parity with io.open(), which implements a try/except to
assure file stream gets closed before an exception is raised.

The fix LGTM, but I have some comments about the test.

- Move spec out of seperate class and into CodecsModuleTest
- Pass invalid encoding to force exception rather than mock
- Specify that a LookupError is raised specifically
