[guusdk]

Fixing an obvious copy/paste issue where setName would incorrectly update the email address of a user with the provided name value. Thanks Tijl!

📝 Walkthrough

Walkthrough

UserMultiProvider.setName now calls the backing provider's setName method. Name changes no longer call setEmail.

Merge Risk: 🟡 Moderate · up to 02fc7

Name changes now update the intended field for providers that support them, but Crowd-backed users can receive an unsupported-operation failure instead of having their name updated. This backend behavior should be handled before merge.

- Line 440: Update UserMultiProvider’s name-update flow around setName and
CrowdUserProvider so Crowd-backed users no longer hit an unconditional
UnsupportedOperationException. Implement setName in CrowdUserProvider if the
backend supports name updates, or explicitly handle that provider as unsupported
before reporting success; preserve existing behavior for other providers.
