Compilation errors on CLI execution include a stacktrace

[JaroslavTulach]

If one creates an erroneous file z.enso:

import Standard.Base.Data.Numbers.Number

plus : Xyz -> Abc -> Number
plus (a : Xyz) (b : Abc) = a + b

and runs it, this is the output:

enso$ ./built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/bin/enso --run z.enso 
In module z:
Compiler encountered errors:
z.enso[3:8-3:10]: The name `Xyz` could not be found.
z.enso[3:15-3:17]: The name `Abc` could not be found.
Aborting due to 2 errors and 0 warnings.
Execution finished with an error: Compilation aborted due to errors.

the exception stacktrace is wrong in this case and has no reasonable meaning. Avoid printing it.
