remove call for recent apps dialog box( not regular recents screen)

This only affects devices with hardware app switch key, virtual key presses do not display this dialog box. This call was removed on the commit that added hardware key remapping because it conflicts with reusing app switch key for any other function, here, https://github.com/TeamBAKED/frameworks_base/commits/jb-4.2/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java . it snuck back into the source here
https://github.com/TeamBAKED/frameworks_base/commit/dc0377bb12acf8829221e47f990e308269216014
This commit included a bunch of changes from AOKP which does not have hardware key remapping yet. I can only assume it was unintentional, must have slipped in with thevother changes. 

Trav or whomever else, im in IRC most days if we need to chat about this one.
