DeviceStateAccessor: fix incorrect initial parameter propagation; r…

…estore ability to connect to devices (#53)

## ♻️ Current situation & Problem
Trying to connect (via SpeziDevices) to a peripheral doesn't work
because the `nearby.onChange` state observer is sent an initial `false`
value, which causes the peripheral to immediately get discarded after
being discovered.


## ⚙️ Release Notes 
- Fix issue that could prevent peripheral connection establishment

Note: this PR supersedes #52 (the difference being that this one is made
from an repo-internal branch, which @PSchmiedmayer said was required for
some of the actions to properly run)
