Installing a version when one is already installed failed

[chriscool]

This is also described in issue #7:

root@3416e74c98e9:/mnt# sharness/bin/ipfs-update install v0.3.8
installing ipfs version v0.3.8
binary downloaded, verifying...
success!
installing new binary to /usr/local/bin/ipfs

installation complete.

root@3416e74c98e9:/mnt# echo $?
0

root@3416e74c98e9:/mnt# sharness/bin/ipfs-update install v0.3.8
installing ipfs version v0.3.8
binary downloaded, verifying...
success!
stashing old binary
installing new binary to /usr/local/bin/ipfs/ipfs
ERROR: Install failed:  error moving new binary into place: open /usr/local/bin/ipfs/ipfs: no such file or directory

sorry :(
your old ipfs binary should still be located at:  /root/.ipfs/old-bin/ipfs-v0.3.8
try: `mv "/root/.ipfs/old-bin/ipfs-v0.3.8" "/usr/local/bin/ipfs/ipfs"`
ERROR: error moving new binary into place: open /usr/local/bin/ipfs/ipfs: no such file or directory 

root@3416e74c98e9:/mnt# echo $?
1

It also fails in the same way when installing v0.3.8 after v0.3.9.

Yes, I was trying to write more install tests, see PR #9.
