WireTests Warnings: session_set_save_handler()

[jlahijani]

Note: I'm using bleeding edge ProcessWire, but these were there before. Using PHP 8.5 (not sure if that matters however).

When running all wire tests, I get Warning: session_set_save_handler() during various tests. Note: not sure if this has to do anything with SessionHandlerDB which I'm using.

Here it is occurring in TEST: InputfieldFieldset:

- OK: module returns InputfieldFieldset

- OK: fieldset label is settable
- OK: fieldset collapsed state is settable

- OK: direct render includes second child name
- OK: children count includes added fields
