Catch exception from parser, log and set run to failed, instead of crashing

[tnachen]

Currently if the parser finds a problem, it crashes the controller:

e.g:

/app/extension-lib/parser.js:32
let values = capturedLine.split(",")[1].split(":")[1].split("|");
^

TypeError: Cannot read property 'split' of undefined
