tests: Ignore unused Textual snapshots on 3.7

The last version of `pytest-textual-snapshot` to support Python 3.7 uses a different naming convention for its snapshot results than the current version. Because of this, once our test suite is updated to use the naming convention required by the latest version, the old version sees all of these new snapshot result files as extra junk not being used by the test suite, and believes they should be removed. Hack around this by programmatically enabling Syrupy's `--snapshot-warn-unused` option for Python 3.7. Signed-off-by: Matt Wozniski <[email protected]>
