Fixed "[Error: ENOENT, no such file or directory '\plugman-tmp1375365605837\plugin.xml'], errno: 34"

I couldn't add any plugin, I just got the error:

```
{ [Error: ENOENT, no such file or directory 'C:\Users\<user>\AppData\Local\Temp
\plugman-tmp1375365605837\plugin.xml']
  errno: 34,
  code: 'ENOENT',
  path: 'C:\\Users\\<user>\\AppData\\Local\\Temp\\plugman-tmp1375365605837\\plu
gin.xml',
  syscall: 'open' }
```

For some reason `git clone` doesn't clone into the right directory when given a relative path. So I changed the relative path to the absolute path, and voila, it worked!


Btw I'm using Windows 7 with "git bash" as command line.
