Short description of error
BIN7400 FBX setting "bake_anim_use_nla_strips": True, fails to export unique animations to each take

Exact steps for others to reproduce the error

When using the export settings "bake_anim_use_nla_strips": True, with "bake_anim_use_all_actions": False, to selectively export actions animations to fbx the resultant fbx has the correct action names for each take but all contain the same animation.

I have attached blend file with a template to export, you just need to fill in the exportpath.

You will see the resulting fbx has the animation data for "up" when you select the down or jiggle animations.

To fix I believe you need to change current the action to match the strip name as it loops though. I am no programmer but something like works to replace the around line 2010 in export_fbx_bin

      for strip in strips:
          strip.mute = False

        #addition begins

          for a in bpy.data.actions:
              if a.name == strip.name:
                  bpy.context.object.animation_data.action = a

        #addition ends

          add_anim(animations, animated,
                   fbx_animations_do(scene_data, strip, strip.frame_start, strip.frame_end, True, force_keep=True))
          strip.mute = True

I have attached the blend file, fbx how it currently exports and the fbx exported with the change above

Problem comes from the new behavior of NLA editor, now if an object has an action assigned, it overwrites any action set in NLA's strips (materialized in the 'virtual' top strip of the editor). Will fix.
