CB-6945 Make Camera plugin independent from File plugin on windows 8

After resolving [CB-6920](https://issues.apache.org/jira/browse/CB-6920) and [CB-6613](https://issues.apache.org/jira/browse/CB-6613) Camera plugin uses native Windows 8 functions to manage files instead of File plugin.

So file plugin dependency is excess and we can remove it.

Fix for [CB-6945](https://issues.apache.org/jira/browse/CB-6945)
