getting field with the changed handle before CustomFieldBehavior knows about it

[i-just]

Description

An error occurred when applying project config with a single section type and an entry type with a field whose handle has been renamed, and when saving a global with a field with a newly renamed handle.

This was caused by the field not yet loaded into the CustomFieldBehavior::$fieldHandles.

Solved in a simpler way via e6d5133

(This is based on the same thing saveField() does for new field handles here:

cms/src/services/Fields.php

Lines 1240 to 1241 in e6d5133

	// Tell the current CustomFieldBehavior class about the field
	CustomFieldBehavior::$fieldHandles[$fieldRecord->handle] = true;
