Handle dynamically loaded completion functions (#79)

Browse Source 
On Ubuntu/Debian, completion functions can be dynamically loaded via
_completion_loader. Since those functions are not visible when
fzf-completion.bash is loaded, we need this special hack to make it
possible to fail back to the original completion function when trigger
sequence is not found.
