Can't do a season pack search in manual search

@miigotu
so remove the condition.

TODO: need to start fallback search. It's not initiated.

@abeloin confirm we can't do a season pack search while manual search? I remember you did some changed in that.
We you first press MS, it starts a episode search not season search. Season search only works in backlog search and dailysearch

Fixes wrong search_mode when manual search and search_fallback is enabled
