Description

SelectQuery.aliasPathSplits doesn't actually add the split expressions, so a test like this generates an exception:

SelectQuery query = new SelectQuery(Artist.class);
query.andQualifier(ExpressionFactory.matchExp("p.paintingTitle", "X"));
query.aliasPathSplits("paintingArray", "p");
context.performQuery(query);

INFO: *** error.
org.apache.cayenne.exp.ExpressionException: [v.3.1-SNAPSHOT ${project.build.date} ${project.build.time}] Can't resolve path component: [Artist.p].

The fix is rather simple - register the aliases in the query metadata (i.e. make the method do what it is supposed to do).
