Incorrectly finds unused translations that are in separate files

[kcarmonamurphy]

Our translations file structure is the following:

app > translations > folder1 > en-ca.yml
app > translations > folder1 > fr-ca.yml

app > translations > folder2 > en-ca.yml
app > translations > folder2 > fr-ca.yml

app > translations > en-ca.yml
app > translations > fr-ca.yml
...

When running ember-intl-analyzer, it incorrectly finds unused translations that are in the files in folder1 and folder2. In our app, we would call them like this.intl.t('folder1.key.for.translation') and this.intl.t('folder2.key.for.translation') respectively.
