test: cover cache and resolver failure cases

Added ERT tests that the per-team collection cache and the resolvers fail soft: pearl--team-collection returns nil and caches nothing on a malformed (missing nodes) or nil response, so a retry refetches and a later success populates the cache; pearl--resolve-team-id returns nil rather than erroring when its backing fetch fails; pearl--custom-views likewise does not cache nil and recovers on a later call. Also dropped a stale pearl--cache-issues binding from this file's cache-reset macro — that variable was removed earlier. 371 tests green.
