Spiral Wrapped Text extension fails if text contains any markup entities

[Yura80]

If text contains any '&' entity, such as &, it produces the following error:

Traceback (most recent call last):
File "eggbot_spiraltext.py", line 400, in

File "C:\Program Files (x86)\Inkscape\share\extensions\inkex.py", line 268, in affect

TypeError: 'builtin_function_or_method' object is unsubscriptable

A small patch is necessary:
