CLI: Remove calls to ast_cli_generator.

The ability to add to localized storage cannot be supported by
ast_cli_generator.  The only calls to ast_cli_generator should be by
functions that need to proxy the CLI generator, for example 'cli check
permissions' or 'core show help'.

* ast_cli_generatornummatches now retrieves the vector of matches and
  reports the number of elements (not including 'best' match).
* test_substitution retrieves and iterates the vector.
