fix(tests): correct testDetectUnencryptedFilesQuery assertion

The migration test writes files that are intentionally unencrypted
(simulating pre-migration state), so asserting encrypted != 0 was wrong.
Replace with a weaker but still meaningful assertion: verify the file
actually landed in filecache (proving the write and query target the same
table), plus the existing numeric-result sanity check.
