bug in function camel_to_underscore

[Szymon Jasiński]

Something isn't right with camel_to_underscore function:

In [1]: from djangorestframework_camel_case.util import camel_to_underscore

In [2]: camel_to_underscore("test")
Out[2]: 'test'

In [3]: camel_to_underscore("TEST")
Out[3]: 'tes_t'

[Szymon Jasiński]

$ pip freeze | grep camel
djangorestframework-camel-case==1.2.0
