do not try to center floating window on itself 

Some apps including XTerm start with a WM_CLIENT_LEADER property
containing their own window ID.  Before this commit, i3 tried to center
such windows onto itself and did it wrong since
`leader->rect == {0,0,0,0}` at this moment.

The first affected commit is 128122e766,
however, before it such windows already was misplaced, but got sanitized
afterward [1].

[1]: 8a3ef3a81b/src/floating.c (L329-L335)

Fixes #3606
