Remove WrongMessageTest

Merge from Widevine repo of http://go/wvgerrit/48841

This test is not providing value to the CDM, as it seems to exist
primarily to validate server behavior. However, it is not doing what
it says it is (the request is rejected because it is using unparseable
garbage data, not because its key ID is unknown) and according to
tinskip@, the behavior it claims to be testing is not valid. (The
licensing service will not fail just because the key ID is unknown.
Indeed, if the test data is fixed to use a valid payload with an
unknown key ID, the test fails because the server does not.)
