its not correct, because also invalid chunking/dav path combinations are tried

@phil-davis please review again, added check if the combinations are valid

[individual-it]

this change will break at least the guests and files_classifier app.
PRs to fix the apps:

• move uploadWithAllMechanisms to helper guests#287
• https://github.com/owncloud/files_classifier/pull/125

[phil-davis]

Validation looks good.
The old code used to specifically do the valid combinations, rather than looping.
