pip fails when project requirement result binary already exists

Bug Description

When trying to Snap the JoinMarket project on Github. I noticed that when running snapcraft for the second time, would fail because a result binary already exists, and pip didn't have a `--exists-action` set.

In the patch, I'm not sure if it would be better to (i)gnore or (w)ipe for the default action.

I've included a patch which fixes the issue for me. I also have included the error message I am getting, along with my snapcraft.yml.

Error message:
