Fix wrong SafeTestsets UUID in [extras] (#74)

* Fix wrong SafeTestsets UUID in [extras]

The [extras] entry for SafeTestsets used the UUID
1e83bf80-4336-4d27-bf5d-d5a4f845583c, which is actually StaticArraysCore's
UUID. As a result Pkg mapped the name SafeTestsets to StaticArraysCore and
applied the [compat] bound "0.0.1, 0.1" to StaticArraysCore (whose registered
versions are 1.0.0 - 1.4.4), making the test environment unsatisfiable. This
broke every test job (Core/NoPre across julia 1/lts/pre) and the Downgrade job
on master.

Use SafeTestsets' actual registered UUID
1bc83da4-3b8d-516f-aca4-4fe02f6d838f.

* Fix wrong SafeTestsets UUID in test/NoPre/Project.toml

The NoPre group env pinned SafeTestsets to UUID
1e83bf80-... whose only registered versions are 1.0.0-1.4.4,
which conflict with the `0.0.1, 0.1` compat bound, causing an
Unsatisfiable resolve. The registered SafeTestsets UUID is
1bc83da4-..., matching the root test env (which passes). Verified
locally: NoPre env now resolves and picks SafeTestsets v0.1.0.
