chore: show error msg (not err code) when installing exts via deeplink/store fails (#1007)

* chore: show error msg (not err code) when installing exts via deeplink fails

When installing extensions via deeplink fails, previous implementation
showed the raw error code returned from the backend interfaces, which
is not user-friendly. We now call installExtensionError() to interrupt
the error code to get a human-readable error message, then show it to
the users.

* fix: correct install extension error when installing via store
