Show a more actionable error message when deployment fails (#1050)

## Changes
* We were not catching bundle deployment errors because the process was
throwing string errors and we don't capture errors which are not
instance of `Error` class in onError.
* Now, we show that the deployment has failed and ask the user to if
they want to see the logs.
