ShellDriver.run() doesn't return output if command times out

[spark5]

When command times out, an Exception is thrown. However, I want to be able to get the partial uart output.

The output is partially contained within the exception. Since the exceptions now get stored within the event, one could match on the exception type and retrieve the output from there. Alternatively the different reporters all show the UART output, but are not coupled to the individual commands.
