METRON-1493 Unhelpful Error Message When Assignment Expressions Fail
When executing an assignment expression that fails, the error message is less than helpful. Prior to this PR the error message looks something like this.
```
[Stellar]>>> p := 0/0
[!] Assignment expression failed
java.lang.IllegalArgumentException: Assignment expression failed
at org.apache.metron.stellar.common.shell.StellarResult.error(StellarResult.java:115)
at org.apache.metron.stellar.common.shell.specials.AssignmentCommand.execute(AssignmentCommand.java:82)

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)
at java.lang.Thread.run(Thread.java:748)
```
This has now been fixed so that you can understand exactly what happened.
```
