Describe the Bug

The commit here: 27a6c48#diff-9cd20785e748deea5b742126c8ad37c2959c1a1c943a21c4d008e988a5600eceR1742-R1743

Removed the capability to have mal_search type be a commalist . It seems to be in an unrelated change about imdb.

From using a python library and the corresponding query, it appears that mal api does accept list for type
