Subject: Fix warnings: window.c: tabline_height(): Np dereference: FP.

Problem    : Dereference of null pointer @ 4978.
Diagnostic : False positive.
Rationale  : tabline_height() shouldn't be called when a tab doesn't
             exist yet (this is, before initialization).
Resolution : Assert function precondition.
