fix(file_upload): Fix columnar and Excel upload forms

[Antonio-RiveroMartnez]

SUMMARY

One of the form fields we changed when working on CSV forms was the not very descriptive "con" field, which was renamed to "database". Now, we are updating Columnar and Excel forms so they both stop displaying an error message. Additionally, we updated our tests.
