Remove explicit empty `""` handling in ConfigParser by EliahKagan · Pull Request #2047 · gitpython-developers/GitPython

One of the benefits of #2035 is that it automatically handles a quoted empty value, i.e. name = "", correctly. Previously, this was handled as a special case, so that it would work even though other quoted values did not work (#1923). Since #2035, it is not necessary to handle it specially. Accordingly, this PR:

• Adds a regression test for values represented as "" (4ebe407).
• Removes the obsolete special-case logic (2f22524).
