Revert r20035 - restore default copy status for Fast Add to "Available"

As noted in https://bugs.launchpad.net/evergreen/+bug/756838, the default
status for "Fast Add" copies has been "Available" since release 1.6.1.0.
Changing the default in the middle of the 2.0 release series would likely
cause more confusion for those sites who appreciate the current Fast Add
behaviour, so this reverts the changes in r20035 and maintains the same
defaults as 1.6.1.0.

Note that in r20264, 2.1.0 will gain two new org unit settings that will
enable sites to control their preferred default copy status for the Fast Add
and Add Volume interfaces.
