Spaces in Path result in Exit status 65

Somewhere in the plugin the path gets cut off at the first space.
Up to some point it gets treated correctly, as the following is printed out correctly:
```
Exporting all variants of /path/containing/s p a c e s.xcarchive
```
But then it fails:
```
error: archive not found at path '/path/containing/s'
** EXPORT FAILED **
Exit status: 65
```
