Major change in 1.5.1 removes empty lines after class definitions

[rixx]

I updated to docformatter 1.5.1 from 1.5.0 expecting no major changes to take place. However, I found that running docformatter removes all empty lines following class definitions, even when there is no docstring present.

I'm not sure if this is intentional, but I expected docformatter to only modify places where there is a docstring present.

(I ran into this face-first because Django generates its migration files with an empty line after class definition, so a patch version upgrade resulted in 171 files changed, 113 insertions(+), 286 deletions(-) for me. Half of that is this issue, the other half that apparently the max line length was slightly shortened?)

Reproduction:

Format this file with docformatter==1.5.0 and docformatter==1.5.1:

class Test:

    default = True

1.5.0 will leave the file alone, while 1.5.1 will output

--- before/test.py
+++ after/test.py
@@ -1,3 +1,2 @@
 class Test:
-
     default = True

This change appears to be related to #130.

docformatter now has a method to determine whether blank lines after a class definition precede a docstring. If so, the blank lines are removed. If not, they are left alone.

Thanks @rixx for reporting the issue. Sorry for the headaches it caused.
