[PATCH] cooker: Allow featureset in error state

[Richard Purdie]

Currently, if an invalid PR service is selected the server will error
with a traceback. This is because its set into the error state and the
setFeature code will then fail since its not in the initial state.

Modifying the featureset in the error state is acceptable, we just need
to ensure we don't trigger a reset, that would happen from whichever
code handles the error.
