Fix searching for movie with release date, #1767

I'm not really known with the inner workings of the query builder, but due to quotes around the movieReleaseDate faulty queries were generated.

Before:
**SearchValue**  Titel:=:+"Some Movie Title" "+(2012)"
**Query**  s.title LIKE '%Some Movie Title\" +\"(2012)%' 

After:
**SearchValue**  Titel:=:+"Some Movie Title" +(2012)
**Query**  s.title LIKE '%Some Movie Title%' AND  s.title LIKE '%2012%'


This fixes zero results for CouchPotato api queries
