Settings: Fix devloper options FC and remove all bug report options

This change: https://gerrit.slimroms.net/#/c/18820/

removed it just in the xml which is a pretty bad idea if java code
still assumes it is there.

Due that we will never need it we remove the code completely.

As well remove bug report in power menu option.
