Returns a list instead of str for "title"

[getzze]

Downstream bug: Diaoul/subliminal#1235

guessit -a "Adam-12 1968 Season 1 Complete x264 [i_c]/Adam-12 S01E02 Log 141 The Color TV Bandit.mkv"

Returns "title" = ["Adam","12"]

subliminal is expecting a str so it leads to TypeError.

The title is "Adam-12" (a str as expected) with only the filename, not the parent folder.
