05448441d3 Fixed issue where multiple csvs could not load 
With the new `create_dataset` approach introduced by PR #2283 (read: mine, sorry!), duplicate
indices in the df would cause a fatal error where the columns could not be referenced by
name. Adding `ignore_index=True` during append allows pandas to assign new indices to
rows, and fixes the issue.

8ec6ac8079 Checking for empty transcripts during character encoding 
This way we can get a plain English exception early, rather than a matrix shape error during training.
