Fixing everyvoice.tests.test_utls

[SamuelLarkin]

PR Goal?

Eric noticed that running the unittests would leave a directory metadata.psv/ where ever you ran the unittests.
Note, that investigating this issue, I realized why the disabled tests marked WIP_* didn't work.
Those tests use a BaseModel and a context and the derived classes were missing a custom __init__() to propagate the context.

This patch looks good, we'll just have to fix what seems to be an unrelated problem in CI.
