Call freeSpace() function before update
Add new function to delete version objects as part of the Activation.
The code update service automatically removes the ubi volumes to make
space, but it does not remove the dbus object associated with the
removed volume. The side effect of leaving the dbus object is that
when freePriority() is called at the end of the Activation, a new
priority value is assigned to all version dbus objects (including the
deleted one) which fills up the u-boot environment variables.
Tested: Verified that after an Activation, there were only 2 priority
values in the u-boot env variables instead of 3, and they corresponded
to existing volumes.
