Alexander Aprelev a9ed5d1d1e [dart/sendandexit] Fix validation of the sendAndExit messages and the test. 
The validation was not actually traversing the message and the test was not actually testing sendAndExit, rather standard message passing.

Brought error messages reported by sendAndExit in line with regular message passing error messages.
