fix: [torrust#581] broken tests using relative paths for fixtures

after introducing figment::Jail for testing. It seems Jail changes the
current dir and that make other tests fails if they use relative path to
load files (in this case fixtures).

A solution like useing the env var CARGO_MANIFEST_DIR does not work with
`cargo next` when building the container. It only worked when you run
the tests with cargo test.

+        Figment::Jail changes the current dir. In the drop function it restores
+        it but that could cause a problem when test are running in parallel.
+
+        For the time being, I have replaced loading the torrent file with
+        this function. This should make the test faster.
+
+        I don't know why this happens only with these two tests.
