t: drop more REFFILES prereqs

Hi,

this is the second version of my patch series that drops the REFFILES prereq from more tests, thereby increasing test coverage of the reftable backend.

There's only a single change compared to v1, addressing Junio's feedback. Please refer to the below range-diff.

Thanks!

Patrick

## Commit message ##
- t0410: enable tests with extensions with non-default repo format
+ t0410: convert tests to use DEFAULT_REPO_FORMAT prereq

In t0410 we have two tests which exercise how partial clones behave in the context of a repository with extensions. These tests are marked to
- require a default repository using SHA1 and the "files" backend because
- we explicitly set the repository format version to 0.
+ require a repository using SHA1 and the "files" backend because we
+ explicitly set the repository format version to 0, and setting up either
+ the "objectFormat" or "refStorage" extensions requires a repository
+ format version of 1.

- Changing the repository format version to 0 is not needed though. The
- "noop" extension is ignored as expected regardless of what the version
- is set to, same as the "nonsense" extension leads to failure regardless
- of the version.
-
- Stop setting the version so that these tests can execute with SHA256 and
- "reftable" repositories.
+ We have recently introduced a new DEFAULT_REPO_FORMAT prerequisite.
+ Despite capturing the intent more directly, it also has the added
+ benefit that it can easily be extended in the future in case we add new
+ repository extensions. Adapt the tests to use it.
