Use cases are all broken and provide unhelpful error messages

[akenmorris]

Something is probably wrong on the data portal, but if this were to happen in the future, we need to improve the error output.

Example:

Step 1. Extract Data
 _____    ___      .
|     |  /   \    / \
|  ShapeWorks Cloud  \
|_____|  \___/  /_____\

Login to ShapeWorks Data Portal successful

Total shape files found in Output/incremental_supershapes/: 0

Data available in Output/incremental_supershapes/  is sufficient, no new data will be downloaded
Done.

Step 2: Sort meshes into batches

For some reason, most of the uploaded datasets are not here, probably the reason why the use cases are failing

Use cases are fixed and messages were improved
