I think this is good now. I adapted the Streaming Tests to always use
`StreamingMultipleProgramTestBase` when appropriate. The earlier problems where
caused by some tests using
`StreamingExecutionEnvironment.getExecutionEnvironment()` without being in a
class that is derived from `StreamingMultipleProgramTestBase`. This caused
those tests to pick up the used environment from another test when run on
travis. (In an IDE the tests would just use a LocalEnvironment because no other
environment would be set.)
