don't specialize convert

This reduces invalidation without changing functionality. On master, and using julia nightly,

This PR removes the invalidation due to convert, and I'm not certain how the getindex one is resolved as well. In any case, specializing convert seems unnecessary, as convert calls constructors that are specialized anyway.
