No, you did everything correctly. The main problem here is that you use 
in your file
the commands \voiceOne and \voiceTwo. These commmands override the stem and
slur directions which are set suitable before. (The stems are invisible, 
but still there,
so the slurs are drawn /over/ the stems and are therefore too far apart).

\new TabStaff = "tab" <<
     \context TabVoice = "upper tab" { \clef "moderntab" \voiceOne \upper }
     \context TabVoice = "lower tab" { \clef "moderntab" \voiceTwo \lower }
   >>

You can use

\new TabStaff = "tab" <<
     \context TabVoice = "upper tab" { \clef "moderntab" \voiceOne \stemDown \slurUp \upper }
     \context TabVoice = "lower tab" { \clef "moderntab" \voiceTwo \stemUp \slurDown \lower }
   >>

as a workaround; the slurs arching under are now too far away; my first attempt isn't aware
of the direction of the slur; I'll try to fix that soon - afterwards, I will try to find a solution for
the \voiceOne / \voiceTwo settings to get rid of the \stem... \slur... commands.

Thank you for your investigations!
