fix(vue2): Remove throwing error on inspect missing vuex module

[Azurewarth0920]

Description

Fix: #1669

Refs: https://github.com/vuejs/devtools/issues/1669#issuecomment-1678899513 As commented above, "Save focused element path in localStorage" → "Revive focusing on refresh page" will easily result in throwing error, I think somehow missing a module is normal behavior, throwing the error is not necessary.
