https://gitlab.com/gitlab-org/gitlab/-/merge_requests/68357 added the
`container_registry_migration_phase1` feature flag. When enabled, this
change caused a `ContainerRepository` model to be instantiated every
time the registry client checked for tags. For projects that had
trailing/leading underscores in their paths, this would trigger a
validation error and cause a
`ContainerRegistry::Path::InvalidRegistryPathError` exception to be
raised while trying to generate the `migration_eligible` flag in the
access token.

Previously this would not cause a 500 error because the access token was
still generated, but the manifest would return empty since registry
images cannot exist for project paths with trailing/leading underscores.

To preserve the previous behavior, we now catch and log this exception
in `ContainerRegistryAuthenticationService.migration_eligible`.

The test used a hard-coded 2021-01-01 as an expiration date, but once
the current date reaches that date this is no longer valid since it's
not in the past. We fix this by using a date always one month from the
current date.
