[Improvement]: Improve error message when there is a mismatch in worker send and recevie pairing

[lochana-chathura]

Description

$subject.

function foo() {
    boolean foo = true;

    worker w1 {
        20 -> w2;
    }

    worker w2 {
    }

}

This above code gives,

ERROR [test_parser.bal:(21:15,23:6)] worker send/receive interactions are invalid; worker(s) cannot move onwards from the state: '[20 -> w2, FINISHED, FINISHED]'

We need to give a meaningful error message.
