[BUG] Send 2 start detection messages instead of 1

[JeromeGalan]

** Which version the bug has been detected **
Luos engine 2.4.2

Describe the bug

When asking many detections with a gate and a button, the start detection is sometimes sent 2 times.
Two cases :
-First image : 2 messages

• Second image : the 2nd messages is broken. Only a few bytes are sent, then Tx enable goes to 0. The message is not sent on the network.

Network configuration

• A Gate
• A Button (wirh autopupdate)

How to reproduce the bug
Ask several detections.

Additional context

• Before versions 2.4.2, this bug could be seen juste before the crash of an autoupdate service (issue [BUG] Assert when pulling from Tx task in case of several detections #222 is now closed).
• Now, app continue to work well. But this behaviour is weird.
• This bug seems to appear only when there are nodes sending autoupdate messaged (to be confirmed...).
