Don't shadow the name textRange.

In TextLine::iterateThroughSingleRunByStyles there is a parameter named
textRange and a local variable also named textRange. This shadowing is a
bit confusing both when reading the code and when debugging, so rename
the local to runStyleTextRange to better describe what it is for.
