[FIX] website_slides: fix wrong comodel name in many2many

Channels uses tags allowing to categorize and filter content. For that
purpose a m2m exists between channels (slide.channel) and tags (slide.channel
.tag). The 2many relationship from tags to channels holds however a wrong
comodel name. It has no impact on code since relationship table is
correctly defined and current code does not use the channel_ids fields
from tags.
