Make CueSerializationTest more realistic

Serializing bitmap cues is currently broken, but this test is
incorrectly passing. This change makes two changes to introduce the same
failure (both changes are necessary, each one alone still passes):

1. Move from Robolectric to an instrumentation test.
2. Trigger the `Bitmap` to be serialized using a file descriptor, either
   by calling `Bitmap.asShared` in the test when constructing the `Cue`,
   or constructing the `Bitmap` from a 'real' image byte array instead a
   1x1 token image.
