When including UARTService instance as an argument for ProvideServicesAdvertisement - .services doesn't return True

When attempting to check for the service in central.py, if uart is listed in the advertisement of peripheral.py, the condition never seems to become true.

**Peripheral.py**
ad = ProvideServicesAdvertisement(hid, uart)

**Central.py**
if ad.complete_name == 'rhf_periph' and HIDService in ad.services:

Result: False

**Peripheral.py**
ad = ProvideServicesAdvertisement(uart)

**Central.py**
if ad.complete_name == 'rhf_periph' and UARTService in ad.services:

Result: False

**Peripheral.py**
ad = ProvideServicesAdvertisement(hid)

**Central.py**
if ad.complete_name == 'rhf_periph' and HIDService in ad.services:

Result: True

[central.py](https://github.com/user-attachments/files/27812962/central.py)

[peripheral.py](https://github.com/user-attachments/files/27812967/peripheral.py)

Start with the provided central.py and peripheral.py examples, then inspect ProvideServicesAdvertisement and how ad.services is populated and compared. Reproduce the HID-only, UART-only, and combined advertisements, and verify that the advertised service checks return the expected results for both services.
