Fly Plan Land item incompatible with ArduPlane due to camera config (of Surveil item?)

[drtrigon]

Whenever we open a saved mission plan (.plan) file that has a surveil element and a plane landing element and try to upload that, we get an error about some camera setting not beeing valid (essentially disabling picture taking). When we download the mission afterward, we see that everything except for the landing elements was uploaded.

Expected behaviour would be just to upload that correctly as the mission plan was uploaded with success before. Only after storing and reopening it does not work anymore.

Steps to Reproduce:

Please provide an unambiguous set of steps to reproduce the current behavior

1. Create a plane mission including surveil and landing
2. Upload it to ArduPlane successfully
3. Store it as .plan file
4. Open the .plan file
5. Try to upload again and see the error
