rope_autoimport: continue on name-defined diagnostics provided by mypy

Previously the autoimport code action did only act on diagnostics which
message contained "undefined name". In my case this did not trigger at
all so that the plugin failed to provide code actions.

This change now additionally looks at name-defined error codes provided
by mypy.
