Add check rcl_node_options_copy invalid out (#671)

Browse source 
* Add bug fix for rcl_node_options_copy

If copy source has options->arguments.impl==NULL
this will cause problem when calling fini
on options dst

* Add test case for bug fix
* Return error when passing not init object
* Remove unexpected usage test
* Init options with non empty arguments
