[abbreviate_artistsort] exception when artist sorted name has no last name part #350
Description
When an artist sorted name only consists of 1 word (e.g., "Josquin" (for Josquin des Prez"), the abbreviate_artistsort plugin throws an exception since surname is not defined in this case.
Here's an example:
Traceback (most recent call last):
File "coverart\__init__.py", line 144, in next_in_queue
StopIteration
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "album.py", line 407, in _finalize_loading_track
File "metadata.py", line 655, in run_track_metadata_processors
File "plugin.py", line 257, in run
File "C:\Users\Xxx\AppData\Local\MusicBrainz\Picard\plugins\abbreviate_artistsort.zip\abbreviate_artistsort.py", line 138, in abbreviate_artistsort
while surname.split(None, 1)[0] == unsort.split(None, 1)[0]:
IndexError: list index out of range
Traceback (most recent call last):
File "coverart\__init__.py", line 144, in next_in_queue
StopIteration
Consider checking for this edge case everywhere in the plugin.
