Failing unit tests

[rienafairefr]

I was unit testing the mobility circuit feature , and I kept having Jest throwing up that snapshots changed.

• tests on ci.inria.fr work fine
• when running the test on my own laptop, the snapshots differ by some whitespaces in a multiselect component.
  example:

● UserForm.vue › should match snapshot 2

    expect(value).toMatchSnapshot()

    Received value does not match stored snapshot "UserForm.vue should match snapshot 2 1".

    - Snapshot
    + Received

I found this:
vuejs/vue-cli#2995
They are also using vue-multiselect, and the problem is similar, there might be a subtle difference in configuration between my machine and the CI one, it might be due to vue-multiselect, not sure, but this is annoying
