OAK-4126: Sugesstion and spellcheck queries throw exception if result contain lucene query character

Note, I have escaped acl check query for spellcheck too. But, I could not come up with a test case where words with special characters are returned for spellcheck (most probably it requires a custom analzer which doesn't break on special chars... but that seems too much effort to add a test for an obvious fix)
