[BUG] Multiple WW enabled on "change WW intent"

[NeonDaniel]

Description

After changing WW to "hey mycroft", both "hey Mycroft" and "hey Neon" may become active. This is probably because the Mycroft precise model had to be downloaded and the skill timed out waiting for the new WW to activate before deactivating the old WW.

Steps to Reproduce

• Install a clean Neon image with NeonCore 23.4.4
• Ask to change wake word to "Mycroft
• Check if both WW are active

Other Notes

• Reported in chat
• Consider extending timeout to something much longer
• Consider a method to query WW model availability and do skill processing asynchronously
