not having issues when used twice in same query

[mstevan]

@mstevan test-set: not.xml test-cases: fn-not-5 to fn-not-16

@team Not behaves weirdly when having two not calls within same query. not("true") or not("true") for example works but not("true") eq not("true")

List of operators to test with because it throws exception: Eq,ne,lt,le,gt,ge,=,!=,<,<=,>,>=

Input: not("true") eq not("true")

Output: ⚠️ ️There was an error.

Code: [XPST0017] (this code can be looked up in the documentation and specifications).

Location information: file:/Users/mstevan/Documents/:LINE:1:COLUMN:15:

Undefined function call; Entered function name and arity doesn't match a defined function signature: "not" called with 1 parameters.

Expected output: true

That's because in JSONiq not is a prefix operator, not a function call.

When serializing back from XQuery to JSONiq, extra parentheses should be added:

(not "true") eq (not "true")
