bug uncovered by these changes microsoftgraph/msgraph-metadata#1209

Recent Dependabot PRs exposed a Graph beta metadata update that added Edm.Guid getByUser overloads under storage.fileStorage. Go generation emitted invalid pointer dereferencing for nullable UUID path parameters.

• Go writer
  • Parenthesize dereferenced Guid / UUID pointer values before calling String().
  • Preserve existing output for non-pointer UUID values.

// before
m.BaseRequestBuilder.PathParameters["userObjectId"] = *userObjectId.String()

// after
m.BaseRequestBuilder.PathParameters["userObjectId"] = (*userObjectId).String()

• Regression coverage
  • Added a Go convention test for nullable UUID path parameter assignment.
  • Keeps coverage for escaped path parameter names at the emission site.
