Remove unused type variable

This merge request removes an unused type variable in [SampleDispatcher.java](https://gitlab.control.lth.se/anders_blomdell/labcomm/blob/master/lib/java/se/lth/control/labcomm/SampleDispatcher.java). This caused warnings when the Java lib is compiled with `-Xlint` since the LabComm compiler outputs code that doesn't use the type variable.
