XaF helper: commands: resolve: fix movie resolution
Commit f436460 introduced a
bug by converting the imdb id returned in the URL form by
imdbpie to the imdb id alone, and doing so for the
'parentTitle' of the media, which represents a series for
a TV episode, but does not exist for a movie. This commit
fixes that behavior by checking that the 'parentTitle'
exists before applying the conversion at its level.

Fixes #119
