Client/server receives message keyword is considering latest parameter as true for 'False' as input #61

[vivektatipamula]

With "latest" parameter of client/server receives message keyword we can select the latest or old messages from message stack. But it is not working properly.

Expected behavior:
latest=true: Client/server should pick latest message from the stack and validate.
latest=False: Client/server should pick old message from the stack and validate.

Actual behavior:
latest=true: Client/server is retrieving the latest message from stack and validating.
latest=False: Client/server is retrieving the latest message from stack and validating.
