Notes

• Screenshot attached

In bug 1836555, we changed the progress update messages from MigrationWizardParent
from being a binary "in progress" and "not in progress" to a series of possible
values defined under MigrationWizardConstants.PROGRESS_VALUE.

We forgot to update the file migrators to use this, and they were still using
the old inProgress flag. This means that the migration occurred, but progress
updates weren't properly displayed.

We had a test for this, but the test was actually broken - it was querying for
the progress groups using a broken query selector. I've fixed the test, added
an additional check to ensure that the progress icons are in the completed
state, and confirmed that the test fails without the fix, and passes with it.
