[latexila] Move singleton instance variables inside get_instance() functions

[Sébastien Wilmet <swilmet src gnome org>]

commit 69ad31f3620cf02f60305171ad9588587e51f023
Author: Sébastien Wilmet <swilmet gnome org>

    Move singleton instance variables inside get_instance() functions
    
    So that the variable is declared in the same place where it is used,
    which is much simpler to understand the code.
