add betsy tests

created on 32bit machine, therefore untested
fix: ReciveReply FIFO/FILO

add concurency, otherwise betsy will stuck at second receive ... now
amiguity without messageExchange declareation is not granted because the
second receive must be executed before the reply is sent, but that is
not testable with betsy

possible scenario: a second client must execute startProcessSync with
the same correlation value before the first reply is sent. Then the
messageExchange attribute paring up matters. then the former/simpler
process will be sufficient
add betsy test OnEvent-FILO-MEx

it is also a FIFOable test... but FILO is the more interesting variant
with onEvent
with another initialization receive the FIFO could be tested with
initial messageExchange operation onEvent
add betsy test OnEvent-FILO-MEx-Pick
fix: remove unused doubled assignment
