Fix T58652: Crash editing shape keys weirdness with instances

This is a second attempt to get the crash fixed. The original fix
worked, but it was reverted by d3e0d7f0825.

Now the logic goes as:

- All pointers which we can not have shared (the ones which are
  owned by the runtime) are cleared.
- The rest of runtime stays untouched.

This seems to be enough to keep particles happy.
