NoSuchKernel used to raise during KernelManager instantiation, but it is now delayed, so our
except NoSuchKernel
isn't catching the error when it's raised anymore.Access kernel_spec to ensure it's raised where it will be caught.
Also removes a redundant warning log immediately before raising, which prevents complete handling of NoSuchError and produces unavoidable duplicate logs.
Test added for runapp, both regression for #993 and simple exercise for everything working correctly.
closes #993
