This PR fixes the following incorrect autocorrect for Layout/EmptyLineBetweenDefs when two method definitions are on the same line separated by a semicolon:

$ cat example.rb
def a
end;def b
end

$ bundle exec rubocop --only Layout/EmptyLineBetweenDefs -a

Before

It results in an autocorrection of the syntax error:

def a
end;d
ef b
end

After

No syntax errors:

def a
end;

def b
end
