This constant also affects the delay for GetPrimaryService calling
OnServicesDiscovered. We shouldn't change the latter to 20 seconds.

Also, on systems using the UI free first match chooser, we should still use 5
seconds.

OK, reverted and I'll leave this up to you guys with the added comment that 5
seconds is a little short when you've realize that your Bluetooth device is off
at the start of the scan (especially since the re-scanning hasn't been
implemented). But, whatever. This is all work in progress. :)
