#8674: Comparison of combinatorial class of words with word paths is broken

This is fine :
{{{
sage: m = WordMorphism('a->adab,b->ab,c->cbcd,d->cd')
sage: m.is_endomorphism()
True
}}}
But we would like the following to be an endomorphism as well:
{{{
sage: P = WordPaths('abcd')
sage: m = WordMorphism('a->adab,b->ab,c->cbcd,d->cd', codomain=P)
sage: m.is_endomorphism()
False
}}}
