Empty translation strings return the key

[brendt]

• Laravel Version: 8.0
• PHP Version: 7.4

Description:

I believe that due to a recent change in \Illuminate\Translation\Translator, empty translation keys now also result in the translation key being show, instead of just the empty string.

This commit added an empty check: 02e983e

empty return true when a string is empty, but an empty translation is a valid one. I believe isset should be used.

Steps To Reproduce:

Here's a simple test case taken from https://github.com/spatie/laravel-translation-loader/blob/master/tests/DummyManagerTest.php

    /** @test */
    public function it_can_translate_using_dummy_manager_using_empty_translation_in_db()
    {
        $this->createLanguageLine('file', 'key', ['en' => '']);
        $this->assertSame('', trans('file.key'));
    }

I may need to note this as a breaking change.

This seems to be expected behavior given current state of code just needs to be documented.

@taylorotwell This also affects Laravel 6 and 7 causing a breaking change there.
