    Bugfix: No methods for queries with qualifier parameters generated.
    
    Cgen should generate a perform-method for queries with qualifiers (e.g. 
"username = $ausername") stored in the datamap, but there is no method 
generated. Queries without qualifiers get a method.
    
    If the alias map for Entity.lastPathComponent is null then an exception is 
thrown later in org.apache.cayenne.map.PathComponentIterator at the line 
"this.aliasMap = Objects.requireNonNull(aliasMap)". This means the qualifier is 
seen as invalid and therefore no perform-method is generated.
