Silent error on dp_dedploy for labkey boards

[camorosi]

When trying to deploy a data product to a labkey board, can run into silent errors where dp_deploy will return TRUE but nothing is written to labkey board. This can happen with incorrect permissions, for example read but not write permissions. Need to add some checks in so this doesn't error out silently.

May be related to how labkey encodes error responses.

Begum just ran into this same error. She tried deploying a data product to a LabKey board, got a TRUE return value, but the daap was not updated. Turns out she didn't have write permissions, read only.
