ts: fix methods builder `.accounts` requiring global programs (#1548)

CHANGELOG.md

@@ -23,6 +23,7 @@ incremented for features.
 ### Breaking
 
 * ts: Mark `transaction`, `instruction`, `simulate` and `rpc` program namespaces as deprecated in favor of `methods` ([#1539](https://github.com/project-serum/anchor/pull/1539)).
+* ts: No longer allow manual setting of globally resolvable program public keys in `methods#accounts()`. ([#1548][https://github.com/project-serum/anchor/pull/1548])
