[CAY-1657] Expression: in-memory comparison requires persistent to be in the same context as exp parameters to match

Description

Artist a1 = // object from context1
Expression e = ExpressionFactory.matchExp(Painting.ARTIST_PROPERTY, a1);

Painting p2 = // object from context 2
assertTrue(e.match(p2));

The last assertion is always false, even though p2 may point to a1's clone in context2... This is inconsistent with using expressions as qualifiers - qualifier parameters that are instances of Persistent can reside in any context - matching works in a context-agnostic way.

I am sure this affects ALL versions of Cayenne, but my testing is done on 3.1 M3/M4
