Duplicate GET:google-tag-settings requests on GA4 setup form load

[aaemnnosttv]

Bug Description

When loading the setup for GA4, a duplicate request is observable for GET:google-tag-settings.

Steps to reproduce

1. Start GA4 set up
2. Observe duplicate request

Screenshots

Additional Context

These calls are from the same effect in SetupMain and primarily due to not including a guard for accounts not being resolved yet.

1. selectProperty ->

   site-kit-wp/assets/js/modules/analytics-4/datastore/properties.js

   Lines 309 to 312 in 8f1c16b

   	updateSettingsForMeasurementID(
   	// eslint-disable-next-line sitekit/acronym-case
   	webdatastream.webStreamData.measurementId
   	);

2. updateSettingsForMeasurementID ->

   site-kit-wp/assets/js/modules/analytics-4/datastore/properties.js

   Lines 545 to 547 in 8f1c16b

   	yield fetchGetGoogleTagSettingsStore.actions.fetchGetGoogleTagSettings(
   	measurementID
   	);

The simple check on accounts only is insufficient because accounts will be received and then sorted in separate actions which causes this to run twice.
