json query does not support ! operator

[vitalz]

Issue occurred for that case:

! - Use to negate a filter: [?(!@.isbn)] matches items that do not have the isbn property. For instance, $.store.book[?(!@.isbn)].

This is one more case:

!= - Not equal to. String values must be enclosed in single quotes.
