Absolutely not, that would be way too subtle for these writers. The waif has obviously taken a personal dislike to Arya, which seems like a violation of one of the cult tenets. If you're nobody, you can't take a personal dislike to someone. So either Jaqen kills the waif and lets Arya go, or the waif does the 'im gonna drag this out instead of killing you when I have the chance' trope, Arya kills her, Jaqen decides that the many faced god has been paid and lets Arya go. Either way, I don't think there is any way she leaves Braavos without seeing Jaqen one last time.Maybe the point of all this is that the faceless men /aren't/ just crazy men willing to kill anyone. The waif is all too willing to kill for the sake of killing, where a faceless man needs to be more discerning. Perhaps Arya refusing to kill the innocent woman was actually her passing a test, rather than failing it.
I'd say more that he's noticed her personal dislike for Arya and is testing her, not setting her up.I had that thought too and he was setting the waif up to be killed. I'll be fine with it but it seems that'd be way convoluted and convenient from an author stand point.
