ApiQueryWatchlistIntegrationTest: Disable temp account in anon edit
Why:
- The test class does anonymous edits, but did not first disable temp user creation
What:
- Disable temp user creation before attempting an anonymous edit
- Enable temp account feature when calling doTempPageEdit
- Remove call to enableAutoCreateTempUser in testShowAnonParamsTemp, as it's no longer needed
