Scott Sanderson 654edaa851 BUG: Clear asset caches when mapping DataFrame. ...

Our DataFrame index resolution logic relies on failed lookups **not**
being cached, but not caching failed lookups is a nontrivial performance
hit when repeatedly looking up sids.  The "solution" here is to clear
the caches after writing in new assets.

The real fix for this is either:

1. Don't construct an AssetFinder until we have the datasource in hand
   in run(), or
2. Don't symbol-map the user's input source if it's a DataFrame.
   Instead we should make our data loaders pre-map the data.
