fix: correctly set compareWith when requesting app refresh with delay (fixes #18998)

[shenxn]

Fixes #18998. When requesting app refresh with a delay, the request will be stored as a string in the form of <appKey>/<compareWith>. However, the address of compareWith is used instead of its value, causing invalid refresh levels being used.
