Investigate discrepancies in questionnaires table

[bjohare]

There are discrepancies in the questionnaires table in which some xform uploads get the form id_string and title set to the randomly generated filename, rather than the values defined in the xform itself:

           name           |              id_string               |                    title

This was a result of some forms having an empty top row on the 'Settings' tab. When the title and id_string were parsed as null, the file key was inserted instead. Resolved by updating forms to remove blank row.
