different errors with augmenting survival models #209

Description

Looking at unit tests for using augment() on workflows for survival models and testing that it properly fails when eval_time is unspecified (see #200). We should get this error:

! The eval_time argument is missing, with no default.

When using the glmnet model, a glmnet-related error is triggered instead of the one for an improper argument call. This doesn't happen when just parsnip is used, so it is most likely a workflows issue.
