Autohelm Errors are Incorrect

[sudermanjr]

When using autohelm with bad credentials (for example), this error message is displayed:

ERROR Tiller not present in cluster. Have you run `helm init`?

When the real error message was something like this:

could not get token: AccessDenied: Not authorized to perform sts:AssumeRole

It would be preferred for autohelm to output the helm error message
