Fix segv when sway is terminating

Browse source 
I've got the following SIGSEGV when terminating sway:
```
Program terminated with signal SIGSEGV, Segmentation fault.
0x00005607dc603af5 in view_unmap (view=0x5607dcb3d350) at ../sway/tree/view.c:599
599		if (surviving_ancestor->type >= C_WORKSPACE) {
```
surviving_ancestor was NULL at that time

This commit is trying to fix this problem.
