protocols method removal of vehicle suffix

[starksm64]

The generation of the test method name passed to the remote execution context is removing the last '_' character thinking that it is a vehicle name. This must be from some earlier incarnation of how the protocol was being handled, but this only breaks test method names like ClientTest#test_web_to_ejb_auth. There is no use of this appending of the vehicle name. This looks to break about 464 tests, mostly in the jpa module.
