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

[Azurewarth0920]

Description

Fix: #1669

Refs: #1669 (comment)
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.
