[dataproxy][s] Rename duplicate fieldIds from dataproxy results.

Browse Source 
Allow the dataproxy backend to be used for viewing files where
the column names are not unique.  This occurs, for example, when
more than 1 column has not been given a column title at all.

Prior to this commit, when encountering such a file, the dataproxy
backend would error-out leaving the user without any feedback as
to what went wrong.
