Fleshlight Launch initializer no longer working

[qdot]

STR:

1. Turn on Fleshlight Launch
2. Start Windows Websocket Server
3. Connect via https://buttplug.world/playground
4. Scan for devices
5. Select Fleshlight Launch
6. Turn on oscillation

Expected:

Fleshlight Launch oscillates

Actual:

Nothing happens, but no errors are thrown in the log either.

If another application such as ScriptPlayer or a WebBluetooth app connects to the Launch, then these steps are retried, the Launch will work fine. This probably means something is wrong with the initialization step.

Initializer was rewritten to use Tx characteristic instead of Cmd characteristic during characteristic rebuilds. Unit test was made to match, causing it to false positive.
