Some fixes to autocompletion in some commands.

Changes applied by this patch:

- Fix autocompletion in 'sip prune realtime', sip peers where never auto completed. Now we complete this command with:
  'sip prune realtime peer' -> all | like | sip peers
  Also I have modified the syntax in the usage, was wrong...
- Pass ast_cli_args->argv and ast_cli_args->argc while running autocompletion on CLI commands (CLI_GENERATE).
  With this we avoid comparisons on ast_cli_args->line like this:
  strcasestr(a->line, " description")
  strcasestr(a->line, "descriptions ")
  strcasestr(a->line, "realtime peer"), and so on..

  Making the code more confusing (check the spaces in description!).
  The only thing we must be sure is to first check a->pos or a->argc.
														      
- Fix 'iax2 prune realtime' autocompletion, now we autocomplete this command with 'all' & 'iax2 peers', check a look that iax2 peers where all the peers, now only the ones in the cache..
