Fix commenting

[supertassu]

closes #394

I'm not exactly sure what the /appeal/respond/{appeal} route is used for, it should be affected by the same bug - but I didn't find any uses of that route outside routes/web.php.

@supertassu originally I think it was to separate administrative comments from replies to the user as they were using different systems. I know it underwent a big change when we instituted templates, so I feel it got deprecated there.

Was likely replaced by this:

Route::post('/appeal/template/{appeal}/{template}', 'AppealController@respond')->name('appeal.template.submit');
Route::get('/appeal/custom/{appeal}', 'AppealController@respondCustom')->name('appeal.customresponse');
Route::post('/appeal/custom/{appeal}', 'AppealController@respondCustomSubmit')->name('appeal.customresponse.submit');

I removed the additional line as there was no adverse affect when I did.
