Tab completion on Array causes ammonite to exit

[dickwall]

If you hit tab to complete on the following line after opening ammonite:

val a = new Array then hit tab to invoke completion, you get a scala.reflect.internal.FatalError and ammonite immediately exits. Example transcript is shown below.

Note that I found this because I created an ArrayElement class for a demo, and hit tab to complete after typing Array. Ammonite probably shouldn't completely bug out in this case even if there is an error in the completion.
