TextLine.handleRun should throw exception for invalid index

TextLine.handleRun caused infinite loop if measureLimit is out of bounds
of start and end parameters (for Spannables). For regular String it used
to throw a similar exception in handleText. This CL verifies what is
written in ApiDoc: measureLimit should be between start and limit
inclusive.
