Update SolveError to include more error messages

[jsh2134]

Errors can sometimes not show useful information

See https://github.com/solvebio/solvebio-python/blob/master/solvebio/errors.py#L62

There are other keys that exist in some errors that are not detail or non_field_errors. For instance 'manifest' is a key thrown in a manifest error. If uploading using a manifest with invalid file format, it includes a very useful error message that gets lost. Is there harm in just handling any error key here? (handle keys with list values and those without)
