[web-bluetooth] Fix "ID" capitalization

jyasskin has just created a new issue for 

== Fix "ID" capitalization ==
In https://github.com/w3c/web-nfc/issues/27#issuecomment-122013007 
@domenic says "Id" should only have an initial capital. @annevk points
 out in 
 that I changed it the other way. 
https://github.com/w3ctag/design-principles/issues/15 doesn't have 
explicit guidance for this yet. We could avoid this by just giving 
`BluetoothDevice`s "id"s instead of "instanceId/D"s.
