Stabilize company import issue assertions

The `/api/companies/:id/issues` endpoint returns every issue in the
company, including system-generated ones. Asserting on absolute
counts made the test brittle whenever an unrelated issue existed
alongside the imported work.

Filter imported issues by title/identifier so the assertion captures
the intent — that the import created matching issues — without being
sensitive to unrelated issues the server produces.
