Fix passing idea version when creating RunProfileState in

```
MavenServerManager.

Noticed this running 'jps -v':
17987 RemoteMavenServer -Djava.awt.headless=true -Didea.version==13.1.2
-Xmx512m -Dfile.encoding=UTF-8
                                                               ^^
```
Not sure what this broke, but it doesn't seem right.
Feel free to do apply the fix manually, as I haven't signed the CLA yet. If merging is preferred let me know and I'll send in the CLA.
