Description of problem:
Older usbmuxd is not erased after updating via yum. So, all older release is still in machine. Can't explicitely delete either.

Version-Release number of selected component (if applicable):
Name        : usbmuxd
Arch        : x86_64
Version     : 1.0.8


How reproducible:


Steps to Reproduce:
1.update fedora20 
2.
3.

Actual results:
Older usb is still present in the system.
$ rpm -qa|grep usbmuxd
usbmuxd-1.0.8-10.fc20.x86_64
usbmuxd-1.0.8-9.fc20.x86_64
usbmuxd-1.0.8-8.fc20.x86_64

Expected results:
Should have only one usbmuxd, I guess.
