🐛 Fix the use of empty styledTextSegments array (#31)

Browse source 
When a TextNode contains empty characters field, getStyledTextSegments returns empty array. This causes a TypeError, when we try to access the properties of the first element of this array.

This change adds a check if the first element of the styledTextSegments exists before using its properties.
