Fix T89805: NLA crash without active track
Was reported for a file which does not have an active track set in AnimData even though it was in strip twek mode (but this was accessed in is_nlatrack_evaluatable()). Root cause for this is not totally clear, but I assume the situation is described as part T87681 (and is fixed in D11052). This patch here just prevents the crash for files that are already in the borked state. Reviewers: sybren Maniphest Tasks: T89805 Differential Revision: https://developer.blender.org/D12085
