How to get \footnote and \footfullcite to work in Fibeamer Beamer theme?

I am using Fibeamer beamer theme(can be accessed here The \footnote and \footfullcite commands don't produce any output. However the references are properly rendered with a frame showing \printbibliography. I suspect this has to do with the footer definition in the theme's style file. However I m unable to get this to work.

Here's a MWE

    \documentclass{beamer}
\usetheme[microtype,faculty=fsps]{fibeamer}
\usepackage[style=numeric,doi=false,url=false,backend=biber]{biblatex}

\author{Karthik}
\title{Presentation title}

\begin{document}
\maketitle
\begin{frame}{ First slide }
Testing citations \footfullcite{Smith2012}
\end{frame}
\end{document}


On page 9 of the fibeamer documentation we find

setspace - This package is used to adjust the leading to 115 %. Loading this package breaks any top-level footnotes without the [frame] optional parameter specified. This is a known bug.

So while \footnote{foo} does not work, \footnote[frame]{bar} does. We now need to tell biblatex to insert [frame] whenever it calls footnotes. This can be done with

\makeatletter
\renewrobustcmd{\blx@mkbibfootnote}[2]{%
\iftoggle{blx@footnote}
{\blx@warning{Nested notes}%
