[REF][PHP8.2] Sort out dynamic properties in api_v3_ReportTemplateTest

[braders]

Overview

Sort out dynamic properties in api_v3_ReportTemplateTest

Before

Dynamic properties in api_v3_ReportTemplateTest cause deprecation warnings in PHP 8.2

After

Dynamic properties no longer.

The $this->entity = 'Contact'; line was no longer needed as createCustomGroup (which used to use it) now defaults to 'Contact'.

Comments

Tons of report tests are failing on PHP 8.2. due to missing tables. I think it's happening because a tearDown isn't running correctly, but I don't expect this to actually address that issue.
