Device.get_attribute_config() requires byte-string

[dschick]

Hi,

I encountered a Segmentation Fault when trying to call the get_attribute_config() method within a Device Class using native Py3 unicode strings.
See more details here: https://www.tango-controls.org/community/forum/c/development/python/get_attribute_config/
The workaround is to hand a byte-string instead of a native Py3 unicode string to the method, so
get_attribute_config(b"attribute_name") instead of get_attribute_config("attribute_name")

I am using PyTango 9.2.5 but it seems also to occur for PyTango 9.3.2.

Thanks @dschick. I made a fix for this in the linked PR.
