Revert "SystemUI: Fix mobile data connection type hiding"

This reverts commit b2aac59c634158f0e3d78f41d36b89c5ab3bbfe2.

This is intentional and is only displayed when 2 connections
are connected at the same time.

E.g.  If you're connected to Wi-Fi with a captive portal, then
3G will remain connected and normal data connectivity will go
through 3G until you have logged in via Wi-Fi.

In that case, the correct display is Wi-Fi with "!" and mobile
with "3G".

Fix the default value for long press on home.

In AOSP the values for this option are different than in CM.
Switch it back to the CM value for opening recent apps.
