fix(statuses): prevent dynamic changes to `keyword_args`

The use of `locals()` in status_reply caused issues due to its dynamic nature.  When `user_id = self.__get_logged_in_id()` was executed, `locals()` dynamically updated `keyword_args` to include the `self` reference again, even after it was explicitly deleted.  This led to a TypeError: `Mastodon.status_post() got multiple values for argument 'self'`.

This commit resolves the issue by replacing `keyword_args = locals()` with `keyword_args = locals().copy()`.  By creating a static copy of the local variables at the time of execution, it prevents unintended modifications caused by dynamic changes to the local scope.

Fixed #388
