Cannot set default policy version

[jameshartig]

The CmpApi and TCModel both hardcode 4 as the policy version. Now that the latest version is 5, there's no way for a CMP to update these to 5 without patching the packages. Even if the CmpApiModel.tcfPolicyVersion is manually set to 5 as soon as cmpApi.update is called with an empty tcString it will create a new TCModel, which defaults to 4, with no way to update the model before the callbacks are fired.

How this should work is that CMPs should read the GVL and use the policyVersion from the GVL to set and use that value. That said i did update the default value in the library with this PR: #474.

@HeinzBaumann we don't always load a GVL before calling cmpapi.update which will create a new TCModel which has hardcoded 4 as the policy version.
